Tri Bourne (born June 20, 1989 in Oahu, Hawaii) is a professional American beach volleyball player.

Bourne and Jake Gibb finished 9th at the 2020 Summer Olympics after replacing Taylor Crabb who tested positive for COVID-19.

After being slowed in the pre-season and the first half of the 2009 campaign with a sore back, Bourne started the final 14 matches of 2009 at outside hitter as a sophomore and was effective.

He attended Academy of the Pacific in Honolulu, Hawaii, but played for Maryknoll High because AOP did not have a volleyball team.

He was also played basketball, where he was the 2007 Interscholastic League of Honolulu Division II Co-Player of the Year (with current Trojan Riley McKibbin) while averaging 10.3 points a game as a center, and was involved in canoe racing with the Outrigger Canoe Club.

He and fellow Trojan Riley McKibbin won the gold medal at the 2007 AAU Junior National Beach Volleyball Under-20 Championships.
