Graham Rowntree will become Harlequins' forwards coach next season, with John Kingston replacing Conor O'Shea as director of rugby.
England's former forwards coach will join the new-look Twickenham Stoop set-up in the summer, with Mark Mapletoft promoted to head coach, the Aviva Premiership club announced.
Ex-England number eight Nick Easter, meanwhile, will take up a role as player-coach, concentrating on defence.
