Odzala National Park, National park and UNESCO World Heritage Site in Cuvette-Ouest Department, Republic of the Congo

Odzala National Park is a large protected area in the Cuvette-Ouest Department of the Republic of the Congo, covering dense rainforest, gallery forests along rivers, open savannas, and wetlands. It sits within the Congo Basin, one of the largest tropical forest regions on Earth, and holds recognition as both a biosphere reserve and a Ramsar wetland site.

Odzala-Kokoua was first protected in 1935 and declared a biosphere reserve in 1977. Denis Sassou Nguesso granted it official national park status by presidential decree in 2001. In 2023 the Forest Massif of Odzala-Kokoua was inscribed on the UNESCO World Heritage List for its biodiversity and its forest elephant habitat.

The park lies in the forest territory of Cuvette-Ouest, where the 2025 internal investigation by African Parks found that park guards had tortured, raped and forcibly displaced indigenous people during the park's construction. The park administration acknowledged these abuses. The same forest holds one of Central Africa's richest primate populations, with western lowland gorillas and central chimpanzees among the species recorded in surveys of the 1990s.

Odzala-Kokoua opened to tourist visits in August 2012, after Wilderness Safaris built two luxury lodges and trained guides and rangers; the camps took six years to become fully operational. Since 2015 the camps have been run by the Congo Conservation Company, founded and funded by philanthropist Sabine Plattner. The park lies in the remote northwest of the Republic of the Congo, so trips need careful planning.

The park contains open clearings known as bais, which forest elephants, buffalo, and gorillas visit regularly to take in minerals from the soil. These spots are among the few places in Central Africa where several large animals can be watched together in the open.
