The Atlantic Equatorial coastal forests, also known as the Congolian coastal forests (French: Forêts côtières équatoriales atlantiques, Spanish: Bosques costeros atlánticos ecuatoriales, Portuguese: Florestas costeiras atlânticas equatoriais), are a tropical moist broadleaf forest ecoregion of Central Africa, covering hills, plains, and mountains of the Atlantic coast of Cameroon, Equatorial Guinea, Gabon, Republic of the Congo, Angola, and Democratic Republic of the Congo.

The forests cover Cameroon's southwest corner, mainland Equatorial Guinea (Río Muni) and the coastal plains of Gabon.

The Atlantic Ocean lies to the west, and pockets of the Central African mangroves can be found along the brackish river mouths and estuaries along the coast.

Along with the neighbouring Cross–Sanaga–Bioko coastal forests ecoregion, the area holds about 50% of the endemic plant life of tropical West Africa.

South Region (Cameroon) is heavily forested and contains the coastal resort of Kribi and the Campo Ma'an National Park.
