The 1981–82 Washington State Cougars men's basketball team represented Washington State University for the 1981–82 NCAA Division I men's basketball season. Led by tenth-year head coach George Raveling, the Cougars were members of the Pacific-10 Conference and played their home games on campus at Beasley Coliseum in Pullman, Washington.

Washington State hosted the first two rounds in the West regional of the 48-team NCAA tournament at Beasley Coliseum.
