The men's basketball tournament at the 2015 SEA Games was held in Kallang, Singapore at the OCBC Arena Hall 1 from 9 to 15 June.

The draw was held on 30 April 2015 at the OCBC Arena Hall 1 during the 2015 SEABA Championship.

Singapore coach Neo Beng Siang was satisfied with the draw, pointing out that they avoided the Philippines and Malaysia until the knockout round.

The Thais opened the semifinals against the Philippines with an 11-point lead at halftime, the first time in the tournament that the Filipinos found themselves trailing at that point.

Singapore caught up with the Thais tying the game anew early in the fourth quarter at 41-all.

Ravena scored on a dunk to restore the five-point lead, and Mark Belo converted a couple of free-throws late in the fourth quarter to win the country's 29th gold medal in 2015 games, and the 17th gold medal out of 18 men's basketball tournaments.
