The 29 year-old Dutch striker joins the club in time for the start of the 2012/13 Premier League season.
Sir Alex Ferguson said: “Robin is a world-class striker with a proven record in England and in European football. His talents need no introduction to our fans – he has scored a number of goals against us in some classic battles with his former club. His movement, finishing and all-round ability are outstanding.”
Robin van Persie said: “It’s an honour to sign for Manchester United. I am looking forward to following in the footsteps of so many great strikers, bringing my experience and playing my part to help the team compete for the biggest trophies in the game. I can’t wait to get started.”
