The Columbus Athenaeum, built as the Masonic Temple, is a historic building in Downtown Columbus, Ohio. It was constructed as a meeting hall for local area Masonic lodges in 1899, and was listed on the National Register of Historic Places in 1997.
The building was first designed in 1898 by Yost & Packard, Kremer & Hart and John M. Freese. It was substantially expanded in 1912-13 under the design of Stribling & Lum, and was renovated further in 1935. By the 1913 renovation, it was considered the largest building used solely for the Masonic order. At a later date it housed a commercial catering venue for weddings and other events.
