Campbell-Gordon joined The Blues in September 2023 and has since made 38 appearances for the club.
The 23-year-old defender has enjoyed a strong start to the season and currently leads the way for assists at the club with four contributions from left back.
“I am absolutely delighted that Ryan wants to commit his future to the club and ourselves.” First-team manager Brad Munn said.
“His performances week in, week out have improved and he’s quickly becoming one of the best attacking full backs across the leagues.
“In my opinion, Ryan is a true example to all players, young and old, that hard work and dedication will improve your performances and thus reap the rewards. I want to thank the club for sharing my long-term vision with this squad which Ryan, I believe, is a huge part of.”
Munn stated: “I’m proud to have played a part in Ryan’s development already and on behalf of all of the management team and the football club, we are thrilled that Ryan wants to stay with us.
“This is only the start of the journey this season but shows real intent that we want to achieve things on the pitch that significantly coincide with the ambitions to make the club as sustainable and as professional as can be.”
Chairman Nick Dargan added: “All at the club are delighted Ryan has committed for this season and beyond. His performances so far have been outstanding and this news will continue to help Brad and the group build positive momentum as the season develops."
Congratulations, Ryan!
