Salonga National Park is a national park in the Democratic Republic of the Congo located in the Congo River basin.

It is Africa's largest tropical rainforest reserve covering about 36,000 km2 or 3,600,000 hectares (8,900,000 acres). It extends into the provinces of Mai Ndombe, Equateur, Kasaï and Sankuru.

The park is in an area of pristine rainforest about halfway between Kinshasa, the capital, and Kisangani. There are no roads and most of the park is accessible only by river. 

Animals in the park include bonobos, Dryas monkeys, Thollon's red colobus, Congo peafowl, leopards, forest elephants, and African slender-snouted crocodiles.
