The South Coast club have confirmed that the 26-year-old has signed a new deal, keeping him at the Vitality Stadium until the summer of 2029.
Tavernier has been ever-present for Andoni Iraola’s side so far this season, scoring his only goal so far in the 1-0 win over Wolves on matchday two.
Speaking to the club’s in-house media team, the attacking midfielder expressed his delight at signing a new deal.
He said: “I’m very grateful for everything Bournemouth have given me over the past few years.
“I’m just delighted that they’ve shown their appreciation of me to sign a new extension and to stay at this club where I’m having such a great time.
“It’s a place that I’ve come to love and it’s my home away from home, so it’s a really good feeling, not just for myself but my family as well.
“We’ve started the season off very well, even in the first game where we gave a good showing against last season’s champions.
“Ever since then, we’ve shown the capabilities that we showed last season, so hopefully, it can long continue.”
