The club said in a statement: "Following the departure of David Moyes as manager, Manchester United has announced that Ryan Giggs, the club's most decorated player, will assume responsibility for the first team until a permanent appointment can be made.
"The club will make no further comment on this process until it is concluded."
Giggs will be tasked with trying to chase down Tottenham and finish in the top six with a potential Europa League place up for grabs.
Sixth place in the Premier League could still secure a place in Europe depending on Arsenal's finishing position. If Arsenal finish top four and win the FA Cup then Hull get a Europa League place but if Arsenal finish in the Europa League places and Hull lose the cup final then the final European spot will go to the sixth placed finisher in the league.
Giggs, who despite being 40 is still a member of the United playing staff, was forced to deny he had a rift with Moyes before their Champions League tie with Bayern Munich earlier this month.
He said at the time: "There is no problem with the manager; I don't know where that came from. The relationship is good.
"Of course as a player you want to play all the time. I normally play every two or three weeks to get the best out of me. The last game was probably my first for seven weeks but you are not sulking, you just have to be ready to play your best for the team."
Giggs is currently third favourite to get the job on a permanent basis. The bookmakers have made Dutch coach Louis van Gaal the favourite with Dortmund boss Jurgen Klopp second in the betting.
