1983–84 Washington State Cougars men's basketball team
The 1983–84 Washington State Cougars men's basketball team represented Washington State University for the 1983–84 NCAA Division I men's basketball season. Led by first-year head coach Len Stevens, the Cougars were members of the Pacific-10 Conference and played their home games on campus at Beasley Coliseum in Pullman, Washington. The Cougars were overall in the regular season and in conference play, last in the standings. There was no conference tournament this season; it debuted three years later. As they had two years earlier, Washington State hosted the first two  rounds in the West regional of the 53-team NCAA Tournament at Beasley Coliseum. This was the third and most recent NCAA Tournament in Pullman; the Spokane Arena opened in 1995 and has hosted several times. The court surface at Beasley Coliseum was tartan (polyurethane) for its first decade; a traditional hardwood floor debuted at the start of this season.
