The new deal will keep Stanislas at the club until the summer of 2021.
“It’s a nice feeling to get rewarded for some good work over the last couple of years,” Stanislas told the club’s official website.
“As soon as it was there I wanted to get it signed and then get my head down and start focusing on improving over the next few years as well.
“I spoke to the gaffer and he was keen to get something done and signed. That shows the faith the manager has put in me – that is something that I really appreciate.
“I just try to do my best every time I get out on the pitch and help the team, whether that be assisting goals, scoring them or contributing to the team’s success. I plan to do that again this season, and maybe take it to another level.”
Stanislas joined Bournemouth from Burnley in the summer of 2014 and has since gone on to make 87 appearances for the club.
