2015 UST Growling Tigers basketball team

The 2015 UST Growling Tigers men's basketball team represented University of Santo Tomas in the 78th season of the University Athletic Association of the Philippines. The men's basketball tournament for the school year 2015-16 began on September 5, 2015 and the host school for the season was the University of the Philippines.

UST made it back to the playoffs after getting eliminated in Season 77. They finished the double round-robin eliminations at first place with 11 wins against 3 losses. The FEU Tamaraws had the same win–loss record but were ranked lower on an inferior -10 quotient. The last time that the Tigers got the top seed was in 1995 when they won their third straight championship. It was also the last time that they won as many as 11 games at the end of eliminations in a season.

They had a twice-to-beat advantage over their Final Four opponent and defending champions, the NU Bulldogs who they defeated in one game to advance to the Finals against FEU. NU has been the Tigers' semifinal opponent for the third time in the last four years. UST became the fifth team in UAAP history to reach the Finals after missing the Final Four playoffs in the previous season.

In Game Two of the Finals series, Kevin Ferrer's 24 points in the third quarter broke the UAAP record for most points scored in a period. He tied his career-high of 29 points in their 62–56 win over FEU to extend the series to a deciding Game Three. In that game, UST was also able to limit the Tamaraws to their lowest scoring output, as they have not scored lower than 60 points in the season. FEU won the series in three games, ending a decade-long wait to claim their 20th men's basketball championship. The Tigers who had faced FEU in the Finals for the first time since 1979 won both games against them in the elimination rounds.

UST recorded the most three point shots made in the season with 89 for a league-best 31% field goal percentage. They also held the highest free throw conversion of 68.4% among all teams.

Graduating players Ferrer and Ed Daquioag were included in the Mythical team selection during the presentation of awards. Ferrer was chosen back-to-back Player of the Week by the UAAP Press Corps for the duration of September 23–27 and on the week of September 30-October 4, while Daquioag received the citation for the period of September 9–13.
