Plymouth trio Kyle Letheren, Ryan Brett and Ben Gerring have all left the club.
Head coach Paul Mariner has decided against renewing Letheren's short-term contract at Home Park, while youngsters Brett and Gerring, who signed six-month deals in the summer, have been allowed to leave.
A club statement read: "Everyone at the club would like to thank the trio for their contribution to the club and wish them great success in the future."
