Geelong have delisted Aaron Black, Stewart Crameri, Ryan Gardner, Cory Gregson, Matthew Hayball and Timm House.
Former Essendon and Western Bulldogs forward Crameri departs after just one year on the club's rookie list, playing four senior games.
Gregson played 39 games for the Cats since making his debut in 2015, but was plagued by a series of foot injuries.
Cats General Manager of Football Simon Lloyd thanked the six for their services.
“We sincerely thank all six players for their service to the club, whether it be over a short or a long period, these players have all made a contribution to Geelong as footballers and as quality people,” Lloyd told geelong.com.au.
“The club wishes them all the best as they embark on their future endeavours.”
