Leon Cort, Mark Gower and Danny Hollands are among 11 players that are following head coach Jose Riga out of the exit door at Charlton.
The club have released defenders Cort and Cedric Evina, and midfielders Bradley Pritchard, Jordan Cook, Gower, Hollands and Danny Green.
Youngsters Ade Azeez, Kevin Feely and Bradley Jordan have also left along with veteran Andy Hughes, whose departure was confirmed at the end of the season.
Riga revealed on Tuesday he was leaving the club despite saving Charlton from relegation. Former Millwall striker Bob Peeters, currently in charge at Belgian side Waasland-Beveren, is favourite to land the vacant job.
