United burst out of the blocks to score after just 37 seconds when Javier Hernandez swept in a delightful Park Ji-sung pass and the hosts doubled their lead after 23 minutes when captain Nemanja Vidic headed in a perfect cross from Ryan Giggs.
A Frank Lampard tap-in after 69 minutes gave Chelsea hope but United deservedly held on and need just one point from their final two games against struggling Blackburn Rovers and Blackpool to secure the title.
A packed Old Trafford crowd rose to their feet before the final whistle to celebrate and United manager Alex Ferguson bowed to them as they chanted "Glory, glory, Man United" after one of their team's most dazzling performances of the season.
With the first move of the game, Giggs put Park through and the South Korean sent an exquisite pass that goal poacher-in-chief Hernandez slotted past Petr Cech to set the tone of the game.
Wayne Rooney unleashed a couple of long-range efforts that Cech was forced to save in an unrelenting United opening period of pressure before Park's scorching shot was parried behind for the corner that led to the second goal.
Giggs sent the corner short and quickly received it back to lift in a cross for Vidic to head home and give Chelsea a huge mountain to climb.
The London side, having climbed several big peaks to get back into the title race after a mid-season slump that put them 15 points behind the leaders, tried to fight back with chances for Salomon Kalou and Didier Drogba.
Lampard's scrappy goal mirrored much of Chelsea's play, as he stuck a foot out to push in a Branislav Ivanovic flick .
Chelsea were lucky to avoid conceding a penalty when Lampard handled in the area and they could not raise their game enough as Ferguson edged closer to a 12th Premier League title.
Rooney continued to pepper the Chelsea goal with shots as United reverted to the high tempo of the first half for the final 15 minutes of the game, while Ancelotti watched helplessly on touchline with his hand in his pocket.
Goals from Kenwyne Jones, former Gunner Jermaine Pennant and Jon Walters condemmed Arsenal to a sixth season without a trophy while buoyant Stoke head for the FA Cup final against Manchester City at Wembley Stadium next Saturday.
Wolves capitalised on poor defending by their neighbours to score twice in 13 first-half minutes through Stephen Fletcher and Adlene Guedioura before Fletcher added a third goal after another defensive mistake by Abdoulaye Meite two minutes after half-time.
West Brom, who have climbed to safety after a run of good results since Roy Hodgson took over as coach in February, replied when Peter Odemwingie scored for the fifth successive league match with a 55th-minute penalty after Guedioura tripped Jerome Thomas in the box.
Although they are still not safe with two games to play, Wolves are now 17th with 37 points, with Blackpool dropping into the bottom three on 36. Wigan Athletic are 19th on 36 and West Ham United bottom with 33.
