The new contract will keep the 22-year-old at Old Trafford until the summer of 2015.
“It’s been a fantastic start to the season for me, breaking into the first team and getting an England call-up,” Cleverley told the club’s official website.
“Having grown up at the club, I’d love to be able to make a contribution to United winning more trophies. We have a squad with great ability and I can’t wait to get started again.”
“Tom is one of the brightest prospects in the English game,” said United boss Sir Alex Ferguson. “For a young boy, he has a good footballing brain which, when coupled with his energy and ability, makes for a player with a fine future ahead of him.
“It’s the United way to encourage our young players to make their mark in the first team and Tom has grabbed that chance with both hands.”
