The 22-year-old, who first joined the club as a junior, will now represent the Hampshire club by carrying its name and logo on his golf bag at events.
Mr Forster said: “It’s a great honour to be named as a club ambassador. I love representing the club in any way I can, and having Basingstoke Golf Club next to my name in national tournaments is a great privilege.
“It’s also great having a fan base back home – having something more than just myself to play for. Trying to impress them and give them something to follow is really cool.
“I’m thankful to have such great members and such strong support. It makes all of this possible, and it feels really good to give something back.”

He is also a contender for the Great Britain and Ireland Walker Cup team, which will face the United States in September.
David Green, general manager at Basingstoke Golf Club, said: “Charlie’s been a part of the club for a long time as a junior member and his dad was involved even before that. The club has seen him come through the ranks and it’s been great to watch him grow from a youngster into the player and person he is now.”
Mr Green added that the club has always supported Mr Forster, and a round of golf together on the new course solidified the decision to offer him the ambassador role.
He said: “We wanted to support him in these early stages of trying to become a top tour player. It’s an exciting time not just for Charlie but for the club too.”
Basingstoke Golf Club moved to a new site in Dummer in 2021 and now features a championship course and a modern clubhouse.
A golf academy, Trackman range, and short-game area are set to open this autumn as part of a £20 million redevelopment.
The Walker Cup team will be announced on Monday, August 18, and Mr Forster hopes his experience on the US west coast will work in his favour.
He said: “I love that team environment and it would be a great privilege if I were to be selected. Cypress Point is an incredible venue.”
