It is a punishment seven months in the making as Ronaldo has been charged for hitting a mobile phone out of a young fan's hand at Everton in April.
The 37-year-old, who is now a free agent following his release from Old Trafford club on Tuesday, had the altercation after a 1-0 defeat at Goodison Park, for which the Portuguese was cautioned by Merseyside Police.
The FA also charged him with improper conduct and an independent panel has handed down a suspension and hefty fine.
An FA statement read: "Cristiano Ronaldo has been suspended for two matches, fined £50,000 and warned as to his future conduct for a breach of FA Rule E3.
"The forward admitted that his conduct after the final whistle of the Premier League game between Manchester United FC and Everton FC on Saturday 9 April 2022 was improper.
"An independent Regulatory Commission found that his conduct was both improper and violent during a subsequent hearing, and imposed these sanctions."
