The Washington State Cougars men's basketball team represents Washington State University and competes in the Pac-12 Conference (Pac-12) of NCAA Division I. The Cougars play their home games on campus in Pullman at Beasley Coliseum, which has a capacity of 11,566.
Beasley Coliseum is a general-purpose arena on the campus of Washington State University in Pullman, Washington. Opened 47 years ago in June 1973, its current seating capacity is 11,671 for basketball. It is the home venue for both the Cougars men's and women's basketball teams of the Pac-12 Conference.
The arena was renamed in 1981 for Wallis Beasley (1915–2008), a long-time sociology professor and executive vice president, shortly before his retirement from the university. He was WSU's faculty representative for athletics in the 1960s and also served as interim university president. For its first eight years, the venue was known as "Washington State University Performing Arts Coliseum."
The building used "space frame" construction, relatively novel at the time. The elevation of the court is approximately 2,550 feet (775 m) above sea level.
The project was approved by the WSU board of regents in early 1969.
