Wayne Rooney said: "I am made up to be staying at United. In August I will have been at the club for 10 years and during that time I have played with some fantastic players and won everything that I hoped I would when I first signed. I now have the chance as one of the club's senior players to help the younger players coming through and to be a part of another great United team.
"The fans have always been a huge part of this club and the support they have given me since my debut against Fenerbahce has been amazing. I am very grateful to all United fans around the world for their continued support.
"I am really excited to be a part of the club's future and want to thank David Moyes and Ed Woodward for their belief and support in me. I am convinced that this is the start of another successful chapter in Manchester United's history."
