The Mill Mountain Zoo is a zoo located atop Mill Mountain in Roanoke, Virginia, United States. When it opened in 1952, the zoo was operated by the City of Roanoke. In 1976, the city turned its operation over to the Roanoke Jaycees. The Jaycees operated the zoo until 1988 when its operation was handed over to the non-profit Blue Ridge Zoological Society (BRZS). The BRZS still serves as the operator and fund raiser for the zoo.
