1940–41 Washington State Cougars men's basketball team

The 1940–41 Washington State Cougars men's basketball team represented Washington State College for the 1940–41 college basketball season. Led by thirteenth-year head coach Jack Friel, the Cougars were members of the Pacific Coast Conference and played their home games on campus at WSC Gymnasium in Pullman, Washington.

The Cougars were 22–5 overall in the regular season and 13–3 in conference play, first place in Northern division. They met Southern division Stanford in a best-of-three series in Pullman for the PCC title, which the Cougars swept in two games.

Washington State advanced to the eight-team NCAA tournament in Kansas City; they defeated Creighton and Arkansas to advance to the final, but lost to Wisconsin by five points.

This remains the most successful season for Cougar men's basketball; WSU has made six NCAA tournament appearances since (1980, 1983, 1994, 2007, 2008, 2024), and the best result is the Sweet Sixteen in 2008.
