The Mill Mountain Zoo is a zoo located atop Mill Mountain in Roanoke, Virginia. Originally opening in 1952, the zoo was operated by the City of Roanoke for its first 24 years. 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).
