Pac-12 Men's Basketball History

Pac-12 men's basketball regular-season champions and conference tournament champions from the league's early Pacific Coast Conference era through the modern Pac-12.

The New Pac-12

The Pac-12 entered a major transition after the 2023-24 season. Oregon State and Washington State remained members of the Pac-12, but both schools competed as affiliate members of the West Coast Conference in men's basketball during the 2024-25 and 2025-26 seasons.

As a result, there was no Pac-12 men's basketball regular-season champion or Pac-12 men's basketball tournament in either 2025 or 2026.

The rebuilt Pac-12 officially launched for the 2026-27 season with nine full members: Boise State, Colorado State, Fresno State, Gonzaga, Oregon State, San Diego State, Texas State, Utah State and Washington State.

The Pac-12 men's and women's basketball tournaments are scheduled to return to Las Vegas beginning with the new conference era.

Pac-12 Men's Basketball Tournament Champions

The conference held its first postseason men's basketball tournament in 1987. The tournament was discontinued after 1990 before returning in 2002. It was played annually through 2024, except for the 2020 tournament, which was canceled.

Pac-12 Men's Basketball Notes

The conference has competed under several names during its history, including the Pacific Coast Conference, Athletic Association of Western Universities, Pac-8, Pac-10 and Pac-12.

The original Pac-12 men's basketball era ended after the 2023-24 season following major conference realignment. Arizona won the final regular-season championship of that era, while Oregon won the final tournament in March 2024.

Oregon defeated Colorado 75-68 in the 2024 championship game at T-Mobile Arena, with N'Faly Dante earning tournament MVP honors.

The conference did not conduct a men's basketball tournament in 2025 or 2026. The tournament is scheduled to return with the rebuilt Pac-12 beginning in 2026-27.
