The Congolian rainforests (French: Forêts tropicales congolaises) are a broad belt of lowland tropical moist broadleaf forests which extend across the basin of the Congo River and its tributaries in Central Africa.

It covers over 500,000,000 acres (2,000,000 km2) across six countries and contains a quarter of the world's remaining tropical forest.

There are over 400 species of mammals in the rainforest, including African forest elephants, African bush elephants, leopards, bongos, red river hogs, chimpanzees, bonobos, mountain gorillas, and lowland gorillas.

The rainforests have 1,000 native species of birds like the grey parrot, brown nightjar and the bat hawk, and 700 species of fish like the Nile tilapia, Nile perch and the giraffe catfish.

[2] Threats to the rainforests include destruction and fragmentation of forests by commercial logging, oil palm plantations, and mining.
