Great Plains Zoo

The Great Plains Zoo is a 45-acre zoo located in Sioux Falls, South Dakota, United States. The zoo formerly was connected with the Delbridge Museum of Natural History, and prior to the closure of the museum, the museum displayed 150 mounted animals, including 38 "vanishing species". The Great Plains Zoo is owned and operated through a partnership between the City of Sioux Falls and the Zoological Society.

The City of Sioux Falls owns the infrastructure, land, and all assets associated with the Zoo and Museum and maintains the grounds. The Zoological Society of Sioux Falls, a non-profit, operates the facility, manages the animal collection, and maintains the grounds within the exhibit. The mid-sized Great Plains Zoo was awarded the "Quarter Century Award" by the Association of Zoos and Aquariums in 2016, marking 25 years of continuous accreditation.
