The 24-year-old former Wales Under-20 international has made 32 appearances for Ospreys since making his debut during the 2022-23 season.
Warren was added to Wales’ Six Nations squad in January after WillGriff John was ruled out of the opening game through injury.
Speaking on his new deal Warren said:
“I’ve had the opportunity to work with some quality, experienced front rowers and been coached by Dunc [Duncan Jones], who has played an important role in my development,”
“There’s some great competition at tight-head and we all push ourselves in training, which is what you want. The next step for me, on a personal note, is to get as much rugby under my belt as I can, and to keep improving.”
Ospreys head coach Mark Jones added:
“We have high hopes for Ben, so it’s great to have him commit his future to the club.
“He’s already beginning to show the qualities of a top-class tighthead and we’re excited to see how he builds on that going forward.
“I know Dunc sees Ben as a strong prospect in our front row, and I’m confident that he will continue to develop under his stewardship, as so many of our front rowers have in recent years.”
