St. John Arena is a multi-purpose arena on the campus of Ohio State University in Columbus, Ohio, United States. The arena was named for Lynn St. John, who served as Ohio State's men's basketball coach and athletic director until 1947. It was designed by Howard Dwight Smith, architect of Ohio Stadium. It opened in 1956 to serve as the home of multiple Buckeye athletic teams, primarily the men's basketball team. Prior to its construction, the men's basketball team played off-campus in the Fairgrounds Coliseum at the state fairgrounds. St. John Arena served as home of the men's and women's basketball teams until it was replaced by Value City Arena in 1998, while the remaining tenants moved to the Covelli Center in 2019. It is still occasionally used by the men's and women's basketball teams
