Richard Dunne let go by QPR
Joey Barton, Rio Ferdinand and Bobby Zamora are also on the way out the door of the relegated club.
Irish keeper Brian Murphy, as well as Shaun Wright-Phillips have also not been offered new deals and will depart when their contracts expire next month.
Dunne, now 34, has spoken of his desire to continue playing but he will have to find a new club to do so, and he will likely have to ply his trade away from the top flight.
Barton, Dunne and Zamora played 24, 28 and 33 games respectively this season but Ferdinand, whose wife Rebecca died from cancer earlier this month, managed just 12 appearances after joining from Manchester United last summer. Wright-Phillips and Murphy struggled to be even bit-part players
On-loan quartet Mauricio Isla, Niko Kranjcar, Eduardo Vargas and Mauro Zarate have all returned to their parent clubs.
However, 36-year-old defender Clint Hill and Alejandro Faurlin, whose contracts are also due to expire, have been offered new deals to stay at Loftus Road this summer while midfielder Karl Henry has until June 30 to exercise his contractual option for a further year.
