1972–73 Washington State Cougars men's basketball team

The 1972–73 Washington State Cougars men's basketball team represented Washington State University for the 1972–73 NCAA college basketball season. Led by first-year head coach George Raveling, the Cougars were members of the Pacific-8 Conference and played their home games on campus at Bohler Gymnasium in Pullman, Washington.

The Cougars were 6–20 overall in the regular season and 2–12 in conference play, last in the standings. The two conference wins were both at home: Stanford in early January in Raveling's Pac-8 debut, and Oregon State in March. This was the last season for varsity basketball at Bohler Gym; the Performing Arts Center (now Beasley Coliseum) opened in June 1973.

Raveling was hired in April 1972; he was previously an assistant at Maryland under Lefty Driesell, and led the Cougar program for eleven seasons.
