Gill Coliseum is a multi-purpose indoor arena in Corvallis, Oregon, located on the campus of Oregon State University. Opened in December 1949, the arena currently lists a seating capacity of 9,301 and is home to the Oregon State Beavers' basketball, wrestling, volleyball, and gymnastics teams. It is named after Amory T. "Slats" Gill, the Beavers' basketball coach for 36 seasons (from 1928 to 1964), who compiled a 599–392 (.604) record.

The court is named for another OSU head coach, Ralph Miller, who led the basketball program from 1971 to 1989. The building also houses a weight room, equipment center, locker rooms, and offices for the Oregon State University athletic department and its teams. Inside, on the south wall of Gill Coliseum is a painted mural of many former players, including Gary Payton, Brent Barry, A. C. Green, Lester Conner, and Steve Johnson.

The elevation at street level is approximately 230 feet (70 m) above sea level.
