Aberdeen skipper Russell Anderson and midfielders Barry Robson and Nicky Low have all signed new one-year deals at Pittodrie.
Dons boss Derek McInnes told the club website: "All three have made important contributions to the season just finished and I'm looking for them to play their part in the progression of the club next season."
Josh Magennis, Scott Vernon and Nicky Weaver are to leave the club, along with on-loan Swansea defender Alan Tate, but the future of Shaleum Logan, who was on loan from Brentford, remains unclear.
McInnes added: "I would like to thank those who are leaving for their contributions to the club and wish them all the very best in their future careers."
