Zoos in the US 2025
The American zoo landscape in 2025 represents one of the most sophisticated wildlife conservation networks globally, with facilities spanning across 46 states and the District of Columbia. These institutions have evolved far beyond simple animal exhibitions to become crucial centers for education, research, and species preservation. The Association of Zoos and Aquariums (AZA) continues to serve as the gold standard for accreditation, ensuring that only the highest-quality facilities receive recognition for their commitment to animal welfare and conservation excellence.
Modern zoos in the United States operate under stringent guidelines established by both federal agencies and professional organizations, with the United States Department of Agriculture (USDA) licensing approximately 2,800 animal exhibitors nationwide. However, what truly distinguishes the best zoos in America is their AZA accreditation status, achieved by fewer than 10% of all licensed facilities. This selective accreditation process ensures that visitors experience world-class animal care, educational programming, and conservation initiatives that directly contribute to global wildlife preservation efforts.
