Gill Coliseum is the home of the Oregon State men's basketball, women's basketball, gymnastics, wrestling and volleyball teams. The arena's capacity is 9,604 for competitions on Ralph Miller Court, and the building also includes a weight room, equipment center, locker rooms and offices for the athletic department and its teams. Named after the late Amory T. “Slats” Gill, who was Oregon State's head men's basketball coach for 36 years, the coliseum spans more than an acre. When it opened in 1949, it was the second largest suspended arch type structure in the nation, with no internal structural supports to hinder spectator views. Gill Coliseum was recently renovated with improvements totaling more than $3.5 million. This included the creation of the Bud and Maxine Ossey Golf Center, which honors the lifetime contributions and volunteer service of a family who have supported their alma mater through gifts of time and philanthropy for more than 70 consecutive years.

Namesake Controversy and Resolution: A team of OSU faculty including researchers, professors, and archivists came together in 2017 to deliberate over several building names that students had called into question due to controversial namesakes. These building names were researched in depth by the Building Names Committee, and resolutions were found for each one. In the case of Gill Coliseum, its name remained the same.
