List Of Zoos In The United States
The United States is home to a diverse array of zoos and zoological parks, which serve as important centers for conservation, education, and recreation. These institutions vary greatly in size and scope, offering a wide range of exhibitions and programs. The list of zoos in the United States includes both accredited and non-accredited facilities, each contributing to the country's rich tapestry of wildlife education and preservation.
Perhaps one of the most famous zoos in the U.S., the San Diego Zoo is renowned for its expansive and innovative habitats. Located in California, it houses over 3,500 animals representing more than 650 species and subspecies.
Situated in New York City, the Bronx Zoo is one of the largest metropolitan zoos in the world, spanning 265 acres of park lands and naturalistic habitats, and is managed by the Wildlife Conservation Society.
Part of the Smithsonian Institution, this zoo in Washington, D.C., offers free admission and is home to over 2,700 animals representing more than 390 species.
Located in Chicago, Illinois, the Brookfield Zoo is known for its cutting-edge exhibits, including the first fully indoor rainforest simulation.
This zoo is notable for being one of the world's largest natural habitat zoos. It spans over 2,000 acres and focuses on conserving species from the African and North American continents.
Zoos in the United States play a critical role in conservation and education. Through breeding programs, zoos work to preserve endangered species and reintroduce them into the wild. Educational programs and exhibits raise public awareness about biodiversity and environmental issues, often partnering with schools and community organizations.
The AZA is a non-profit organization that represents accredited zoos and aquariums in the United States. Accreditation by the AZA is a mark of excellence in animal care, veterinary programs, and conservation efforts. As of 2025, there are 238 AZA-accredited zoos and aquariums in the US.
Zoos face various challenges, including financial constraints, ethical debates about captivity, and the need to constantly innovate to provide enriching environments for animals. However, they also present opportunities for research, conservation, and education, which are pivotal in fostering a deeper understanding of the natural world.
