The Omaha Athletic Club was a social club building located at 1714 Douglas Street in Downtown Omaha, Nebraska, United States. The idea of such a building in downtown Omaha originated in 1915 when a group of Omaha businessmen, including George Brandeis, met to discuss its establishment. The club was opened with public tours on December 12, 1918. A members-only gala was held December 14, 1918. The gala had two dinner seatings, one at 6:30 pm and a late supper at 8:30 pm. There were 1,500 members at the time the club opened. Total membership was limited to 2000 members.
