World Gorilla Day

Join us at the Cincinnati Zoo on September 23 and 24 to celebrate gorillas! In honor of World Gorilla Day on September 24, we’re celebrating gorillas all weekend long! On September 23 and 24, stop by Gorilla World to learn more about gorillas, see their enrichment, and get entered to win a rare opportunity to see a training session with the gorillas and their care team!


Western lowland gorillas are a critically endangered species. For over 20 years, Cincinnati Zoo & Botanical Garden has been supporting wild western lowland gorilla conservation work in the Republic of Congo.

Some of the biggest threats gorillas face are human encroachment, poaching, and zoonotic disease. It has been estimated that about 2,000 gorillas are lost on an annual basis. The Cincinnati Zoo & Botanical Garden has been acting over the last two decades to help make a difference in western lowland gorilla research and conservation by supporting the Mbeli Bai Study in the Nouabale-Ndoki National Park, located in the Republic of Congo. Mbeli Bai is the longest-running field study of western lowland gorillas that have observed and provided insight on gorilla behaviors and social dynamics.
