The 29-year-old had been previously linked with a move to join Jose Mourinho at Real Madrid but on Monday he put pen to paper on an extension to stay at Old Trafford for at least the next few years.
"Ever since I arrived at United, it's been a dream come true playing here," Evra said in a club statement.
"The fans, the players, the manager and the staff all work hard to make this club the best in the world.
"I have won a lot in the last five years, but I want to win more and I know that's the mentality of everyone here."Evra has established himself as one of the world's top left-backs since his £5million arrival from Monaco in 2006, helping United land three Premier League titles, a Champions League, plus three League Cups.
He has always been a popular figure amongst the United support and his occasional bizarre outbursts - he recently claimed Arsenal was a fabulous football centre but mocked their inability to win trophies - have only reinforced that view.
His links to Monaco will make him a hate figure amongst the Marseille support when United head to the south of France for Wednesday's Champions League encounter with Didier Deschamps' men.
But Sir Alex Ferguson has no fears about Evra handling the abuse and, at a time when the most experienced members of his squad are beginning to end their careers, reckons the defender's influence will become more apparent.
"Patrice is unquestionably one of the world's best left-backs," said the Scot.
"He has developed into a key character in the dressing room and it is great that he has committed himself to the club.
"His experience and skill will be increasingly important to us."
It is speculated that Evra's new contract will see his wages increased from £70,000 to £90,000 a week.
