Beasley Coliseum is a multi-purpose arena on the campus of Washington State University in Pullman, Washington. Opened 44 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.
