Bottas led virtually every lap at the Sochi Autodrom after passing pole-sitter Sebastian Vettel at the start before holding off a late charge from the Ferrari driver in the closing stages.
Vettel crossed the line less than one second behind Bottas to extend his lead over Hamilton to 13 points.
Kimi Raikkonen completed the podium places while Hamilton, who has been mysteriously off colour all weekend, ended up a mammoth 36 seconds behind his team-mate.
Vettel was the overwhelming favourite to claim his third win from the opening four races after securing his first pole position in nearly two years, and with Raikkonen alongside him, Ferrari's first front-row lockout since France in 2008.
But it was Bottas, the Finnish driver who has replaced defending champion Nico Rosberg at Mercedes this year, fastest out of the blocks when the lights turned green.
Bottas starting from third immediately pulled alongside Raikkonen before using the tow off Vettel's Ferrari to take the lead on the 220mph run down to turn two.
It was just what the doctor ordered after Bottas' disappointing showing in Bahrain a fortnight ago where he started from pole position but was ordered to move out of Hamilton's way before finishing a distant third.
For Hamilton, he started well, but was caught up in a Raikkonen-Daniel Ricciardo sandwich and had to settle for fourth in the opening exchanges. Indeed that is where he would finish on a desperately disappointing day for Britain's triple world champion.
It was a bad day again for Fernando Alonso - who failed to even start the race after his Honda engine packed up as the Spaniard made his way to the grid. And Britain's Jolyon Palmer had another day to forget.
Palmer, who crashed out of qualifying on Saturday, was in the wall at turn two, although it looked as though Romain Grosjean was at fault.
The Haas driver bumped into Palmer, who lost control of his Renault and then inadvertently took both he, and Grosjean out of the race.
"For f*** sake, I am out," Palmer bemoaned on the radio. "He [Grosjean] was too ambitious," Palmer added. "If you come in from the inside, it always bunches on the apex. I had cars outside me. I had to turn the corner and hope he used his brain."
The safety car was instantly deployed before returning to the pit lane at the end of lap three.
From there Bottas took charge, but Hamilton, in the sister Mercedes, was having a race to forget. The British driver, who has won two times in Sochi, was having trouble with the soaring temperatures on his Mercedes car.
"There's something wrong, I keep getting vibrations," Hamilton said. Later, he added: "Why is my car overheating, guys? I am out of the race now."
He was certainly out of contention for the victory, and despite getting to within two seconds of Raikkonen, never threatened the Ferrari driver for the final place on the podium. He finished 25.3 seconds behind the Finn.
At the front, Vettel stopped seven laps later than Bottas, in an attempt to leapfrog the Mercedes man. But despite ending the race on fresher tyres he was unable to get close enough to Bottas to prevent him from winning the first race of his grand prix career. Bottas is now just 10 points behind Hamilton in third place in the championship.
Max Verstappen finished fifth for Red Bull with Sergio Perez sixth. Russian President Vladimir Putin arrived midway through the race before taking his seat in an awkward sandwich between Bernie Ecclestone and Chase Carey, the American who deposed him as the sport's chairman.
A new winner
It may not be the result many expected but it paints a different picture on the season ahead of Spain and that's no bad thing.
Look at the Mercedes bromance
The results are in
It was great to see Lewis Hamilton go straight over and and congratulate his teammate at the earliest opportunity. Mercedes is clearly a happy home these days...
But this is Bottas' moment. Look at that smile!
I think everyone is happy for him
Is there a more universally liked driver on the circuit?
Congrats @ValtteriBottas on your first win in F1! ����������������— Fernando Alonso (@alo_oficial) April 30, 2017
Here is your podium
We have our winner!
Valtteri Bottas wins the Russian Grand Prix ahead of Sebastian Vettel and Kimi Raikkonen.
He becomes the 107th different winner in Formula One.
Congratulations to the Finn.
Lap 52 of 52
Massa is in between Bottas and Vettel and the Ferrari driver is not happy!
"What was that?"
Lap 51 of 52
Bottas needs to get past Massa who is hoplding him up as he attempts to get away from the Ferrari of Vettel.
Lap 51 of 52
The German gets the DRS open. Bottas needs to keep his calm to get his first win. He is closing in on the Mercedes, but wouldn't it be better for the Championship to see a different winner.
Lap 50 of 52
Vettel can't seem to get in the DRS zone but he is cutting that gap as quickly as he can.
Will it be the young upstart or the veteran standing on the top step at the end of the day.
Lap 49 of 52
Vettel cuts the gap to 1.2s and you have to wonder how much that late stop wlll give the Ferrari the advantage.
There is something on the track at turn five. will this decide the race for them or will there be more drama?
Lap 46 of 52
Bottas is remaining calm as we get into the last six laps of the race. Vettel is closing the gap but not within that 1s window to use his DRS.
Bottas leads from Vettel, Raikkonen, Hamilton and Vertsappen. Perez, Ocon, Hulkenberg, Massa and Sainz make up the top ten.
Stroll remains in 11th, followed by Kvyat, Magnusson, Vandoorne, Ericsson and Wehrlein.
Lap 44 of 52
Is Bottas going to win his first ever Grand Prix?
His Mercedes teammate is protecting the car. I never thought I'd see the day Hamilton would be settly for fourth.
Massa has dropped down to ninth after a slow puncture and it's disappointing for the Williams driver who was comfortable in sixth.
Lap 42 of 52
Vettel is now just 1.691 behind Bottas. Is the Mercedes in trouble or can he hold on?
Lap 41 of 52
Clearly Vettel feels like his fresher tyre's are going to give him the adavantage as we have just 11 laps left.
It feels like the podium is confirmed, with Hamilton over 13s behind Raikkonen in fourth.
This track isn't known for its overtaking, so it's hard to see ,much changing between now and then.
Lap 39 of 52
Vettel is closing down on Bottas with those fresh tyres and the gap is down to 2.385s.
The Ferrari driver is not looking to give the race win up without a fight.
Hulkenberg is the only driver that hasn't stopped as we near lap 40. I'm not sure if it's smart of silly...
Lap 38 of 52
Can't help but feel this is a straight shoot-out between Bottas and Vettel with Raikkonen 6.3s behind his teammate.
I did predict only one Mercedes would make the podium this week, I just picked the wrong one.
But this is F1, anything could happen.
Lap 36 of 52
It feels like Hamilton is out of the podium race today as he's 22.765s behind his teammate who leads the race.
I think we should send our prayers to Bono, his race engineer.
Lap 35 of 52
Vettel pits this time and Bottas regains the lead. Somehow he comes out ahead of his teammate and he is gunning for the Mercedes.
Bottas leads from Vettel, Raikkonen, Hamilton, Vertsappen, Hulkenberg, Massa, Perez, Ocon and Sainz.
Stroll is 11th with Kvyat, Magnusson, Vandoorne, Ericsson and Wehrlein making up the 16 cars still involved.
Lap 34 of 52
No he is not. Vettel is still out on track.
If this doesn't work, well...
Lap 33 of 52
Remember that Vettel has to pit because they have to use two different tyre's.
Raikkonen didn't realise that it was Bottas leading the race and not Hamilton which says a lot about the way things normally are.
Vettel is coming in....
Lap 31 of 52
Vettel has been told to stay out by his engineer. The German driver has to maintain these speeds if it is going to work to his advantage with a 19.573s gap between him and Bottas.
It's Hammer time
The Brit is on his way into the pits and that leaves Vettel as the only car of the top four not to change yet.
Lap 30 of 52
Raikkonen is in the pits which is a surprise because the driver that leads normally comes in first.
Vettel and Hamilton are still yet to stop.
Lap 29 of 52
Verstappen sits in fifth with Hulkenberg, Massa, Perez, Ocon and Sainz making up the top ten.
Then we have Stroll, Kvyat, Magnusson, Vandoorne, Ericsson and Wehrlein.
Lap 28 of 52
Ferrari are trying to take advantage of Bottas' pit-stop but he has the back-markers to get around.
Vettel leads from Raikkonen, Hamilton and Bottas.
Lap 27 of 52
Ocon is in the pits and the supersoft tyres are the boots of choice.
Bottas is pitting.
Who will jump first?
None of the top four have pitted and you have to wonder who will take the initiative and possibly, the advantage.
This picture explains why his race is over.
Lap 25 of 52
Hamilton is extremely chatty today.
Bottas is being held up by the back markers who eventually move out of the way.
Lap 24 to 52
It seems that Hamilton's problems are less of a problem. Vettel's lap times are improving, is he getting ready to pit or are his tyres in better condition than the others.
Also, it seems like everyone has blisters.
It's pit time
We wait to see who will take the best advantage of their rivals stopping.
Perez and Ocon are now up to sixth and seventh.
Lap 22 of 52
Verstappen is having problems with blisters on his tyres so we can expect him to pit soon before it becomes a problem.
Vettel has also admitted to having the same problem.
Massa stops and rejoins the race in 10th.
Lap 21 of 52
Mercedes tell Hamilton that Bottas is also having the same issues but he has the benefit of being in free air as the Finn leads Vettel by 5.6s at the end of lap 20.
Complete choice of when to stop means the teams are in far more control nd we may see who are the master tacticians.
Low degradation on the tyres, which means that drivers and teams can more or less choose when they want to stop. #RussianGP— Pirelli Motorsport (@pirellisport) April 30, 2017
Lap 18 of 52
There is a gap of 14s between Hamilton in fourth and Verstappen in fifth.
The top four looks decided already, but there are still plenty of points to race for.
Lap 17 of 52
Bottas is now 4.519s ahead of Vettel, but the Ferrari man has just set the fastest lap.
If it stays like this it could blow the Championship race wide open.
Raikkonen is a further 4.5s behind his teammate and Hamilton a further 4s back.
Engineers: "Okay Lewis, we are hot on temps."
Hamilton: "Why is my car overheating guys? I'm out of this race..."
I can tell you that his tone is not a happy one and he is now 12.570s behind his teammate and race leader.
Lap 14 of 52
Despite the Ferrari being so much faster for most of the weekend, they can't seem to close the gap to Bottas.
The Finn leads from Vettel, Raikkonen, Hamilton, Verstappen, , Massa, Perez, Ocon, Hulkenberg and Magnusson.
Sainz is 11th and followed by Kvyat, Stroll, Vandoorne, Wehrlein and Ericsson.
Out so far
At lap 13 we've already lost Alonso - who didn't start, Ricciardo, Palmer and Grosjean.
Palmer is not happy
After failing to complete another race he feels he wasn't at fault.
Lap 12 of 52
Hamilton not happy with his P4 as this power issue continues and he's now 9.566s behind Bottas.
Lap 11 of 52
Magnusson: "Did you talk to Charlie [Whiting]? It cannot be right!"
The Haas driver is referring to a 5s penalty for breaking the track limit rules.
His team basically tell him to deal with it. In the nicest way possible.
Vandoorne also has one for the same discrepancy.
Mercedes winning the social media game at the moment
Lap 9 of 52
Bottas continues to increase his lead and he is now 3.147s ahead of Vettel.
Great race for Force India so far with Perez and Ocon in seventh and eighth, respectively.
Local boy Kvyat is down in 12th.
Ham in trouble
Hamilton seems to be having problems with his power unit. they're asking him to cool the car which obviously means less power.
He is already 7.818s behind his teammate who leads the race.
Lap 8 of 52
There will be no further action regarding Stroll and Hulkenberg.
Ricciardo is out!
The Red Bull mechanics tell the Australian that it is terminal.
Lap 6 of 52
Here is how they look at the start of lap six.
Lap 5 of 52
Ricciardo has a problem! His right rear brake is on fire.
That will likely be the end of his race as he limps back to the garage.
The incident involving Stroll and Hulkenberg will be looked at.
Lap 4 of 52
There are the green flags and Bottas took advantage of the clean side of the track at the start. Although it was surprising to see Vettel's weak fight to hold onto his lead.
It will be coming in now. Lap 3
Watching the replay
Hamilton was basically the filling in a triple-decker sandwich with Red Bull and Ferrari the break or gluten-free substitute.
Lap 3 of 52
We have a safety car and the incidents at turn two are under investigation.
Btw, we should thank Palmer for answering my question so early.
Stroll also spun on the track but looks like he will continue his race.
Bottas leads from Vettel, Raikkonen, Hamilton, Verstappen and Massa. This restart is going to be fun.
What a start
We only have 17 cars on the track, Alonso didn't start.
Hamilton and Bottas were all over Raikkonen, the Finn in the Mercedes took the lead at turn two but Hamilton couldn't get the jump on his rivals.
Palmer and Grosjean are out after the Brit crashed into the Haas.
It is all going on.
Lap 1 of 52
Bottas is in the lead on the long straight and the Mercedes were on the Ferrari straight away.
We are getting a safety car after Grosjean and Palmer make contact on the track at turn two.
And we are off!
Alonso is already out of his car and we have an extra formation lap. this is getting silly now and you can't help but feel for him.
Some information from Pirelli
This will work for Bottas, in particular...
With just one stop expected, the start will be even more crucial. Note that positions 2,4, and 6 are on the ‘dirty’ side of the grid. #F1— Pirelli Motorsport (@pirellisport) April 30, 2017
The cars are off on their formation lap and thankfully everyone - including the McLaren's - get away. Although Alonso is suggesting he already has problems.
McLaren mechanic: "Try again Fernando."
Alonso: "I've tried already. Try yourself."
Wehrlein, Ericsson and Vandoorne are the only cars on the super softs, everyone is on the ultra and we only expect a one-stop race.
Massa is ready
Five minutes until lights out
I'm ready. I hope you are. And we all hope the driver's are.
Get comfortable and get excited because we could be in for a cracker.
Ten minutes to go
I dunno about you but I am ready for the race to start. I have so many questions.
- Will Vettel win for the first time in Russia?
- Can the Mercedes take advantage of that long straight at the start?
- Will Palmer finish a race?
- Will we see a crash?
- Will we see something other than a one-stop strategy?
- will the Red Bull of Verstappen last the race after their patch job?
- Will Toto Wolff bang another table?
The cars are on the grid
20 minutes until lights out so it may be the perfect time to get your drinks, get your snacks and get comfortable before the fun starts.
Your starting grid ladies and gentlemen
Here is how the grid will look at the start of the Russian Grand Prix
NOTE: Sainz penalised three grid places for causing a collision at the previous round. Vandoorne penalised 15 places for use of additional power unit elements.
The pitlane is open
This is your 30 minute warning for the fourth race of the 2017 season at Russia's Sochi Autodrom.
Toto Wolff on why the Mercedes weren't as fast as the Ferraris
"Because they had the quicker car..."
"We have a very quick car but she's a bit diff at times, like many of the good ladies. We have all the ingredients to be very strong."
A relaxed Vettel ahead of the race
I wonder if he's listening to 'The Bangles - Walk Like an Egyptian' again....
Will we see more Dad dancing on the podium this weekend?
Some Sochi info for you
The Sochi Autodrom is holding it fourth post-war race and Mercedes have won the previous three. Hamilton won the first two, before Nico Rosberg led from the front last year. Prior to today, they have led all 159 laps at the circuit.
The race will consist of 53 laps,with 18 turns and two DRS zones.
Rosberg holds the in-race lap record of 1:39.094, which he achieved last year.
It's a semi-permanent track and is more like the street circuits of Monaco and the like, with those right-hand turns.
It's fair to say that surviving that long straight and run from turn one to turn two could set a driver up for a good start to the race.
Who do you think will win?
There is still time to vote for the driver you think will be smiling at the end of the race
Christian Horner on Verstappen's issue
Horner said: "Unfortunately we got a water leak and hopefully the guys have come up with a fix. they're working hard to make sure it's race fit. It's like getting the car through an MOT..."
"We had to take the engine out last night, which was new for today, so Max has gone back to his old engine..."
It will be interesting to see if Verstappen can drag his car through the Sochi version of an MOT.
F1 fans enjoying their day
Predict the podium
There is still time to challenge me and pick your top three for the end of the day. Leave your predictions here.
After three races
Ahead of today, this is how they stand:
It appears that the leak is being dealt with and they won't have to change the engine which will be a relief for the Red Bull team and the driver, who has admitted he only expects to finish as high as fifth.
Track parade underway
It looks like Vettel and Hamilton are taking the Joshua and Klitschko stance to competition.
More misery for Max
We've just heard that Max Vertsappen may be facing an engine change after a leak was found. We'll bring you more as we know it.
It has not been the best start to the season for Red Bull, outside of china when Verstappen came third.
Saturday recap from Sochi
In case you missed it, here's a little reminder of what happened yesterday...
Sebastian Vettel stormed to pole position for the Russian Grand Prix on Saturday, ending a run of 18 poles for Mercedes.
Vettel, the Formula One leader, shaved 0.059 seconds off his Ferrari teammate Kimi Raikkonen's leading time, claiming his, and Ferrari's, first pole since September 2015.
The German will be looking to claim his third win of the season on Sunday and extend his seven-point standings lead over Mercedes' Lewis Hamilton.
The Mercedes duo of Valtteri Bottas and Hamilton qualified third and fourth respectively after failing to dislodge Vettel with their last-lap efforts. In a sign of how far ahead the top two teams are compared to the rest, Hamilton was more than a second faster than fifth-placed Daniel Ricciardo's Red Bull.
The Sochi track has previously suited Mercedes, which had been looking to strike back at Ferrari after Vettel won the last race in Bahrain.
Still, Bottas feels he and Hamilton could ambush the Ferraris at the first corner on Sunday.
Vettel suggested on Friday that Mercedes was concealing its true pace after Ferrari led the time charts in practice. Despite failing to make the front row, Bottas and Hamilton did close the gap to Ferrari - with Bottas just .095 off Vettel's time.
Vettel's pole sets the stage for a much more competitive Russian race than any of the previous editions, which were all battles within the dominant Mercedes team.
The driver on pole has won two of the three Russian F1 races so far, the exception being in 2015 when Nico Rosberg retired with a throttle problem, handing victory to Hamilton.
Jolyon Palmer endured a miserable day, qualifying 16th after he lost control on a curb and crashed into the barrier. That was scant reward for his Renault mechanics, who earlier rushed to change the engine on Palmer's car when the previous power unit failed in the third practice.
Hello and welcome to the lap-by-lap coverage of the Russian Grand Prix.
After yesterday's dramatic qualifying I think we could be in for an exciting day.
