Moukalaba-Doudou National Park is a large protected area in Nyanga Province in southwestern Gabon with diverse landscapes and ecosystems.The park spans across rainforests, mountains, dry grasslands, lakes, and river systems that support different plants and animals.

The World Wildlife Fund began a development programme in the park in 1996. On 20 October 2005 the site was added to the UNESCO World Heritage Tentative List in the Mixed category, recognising both cultural and natural values.

Local communities continue to share the landscape with protected wildlife, maintaining a balance between their traditional practices and conservation efforts.The area represents how people and nature can coexist in the same space over time.

The park lies in southwestern Gabon, in Nyanga Province, and covers 4,500 km2 of humid rainforest and savannah grassland. Access is by road from the coastal towns of the region; the WWF has run a development programme here since 1996. Plan for wet forest conditions and check conditions locally before setting out.

The park is known for one of the highest primate densities in Gabon, with gorillas and chimpanzees among the species present. It was added to the UNESCO World Heritage Tentative List on 20 October 2005 in the mixed cultural and natural category.
