The former England international was allowed to leave Old Trafford as a free agent after the Red Devils decided not to extend his contract. Ferdinand joins his centre-back partner Nemanja Vidci to leave United after the end of the last season.
The 25-year-old confirmed his medical with the newly promoted Premier League side on Twitter.
“Thumbs up re medical now on to the the exciting part #Signature EnRoute to Loftus Road…. #QPR,” Ferdinand tweeted.
