Angolan colobus monkeys are found from eastern Nigeria through Cameroon, eastern Gabon, northern Congo, the central African Republic, northeastern Zaire, Uganda, Ruanda, Ethiopia, Kenya, and northern Tanzania. Angolan colobus monkeys are found in various habitat types such as gallery, montane, lowland, and bamboo forests. They are also found in savannas and swamp lands. This species inhabits primary and secondary lowland to montane forest up to 3000m (Rowe, 1996; Grzimek, 1990).
