Osteolaemus is a genus of crocodiles.

[1][2][3] They are small, secretive crocodiles that occur in wetlands of West and Middle Africa.

They are commonly known as the African dwarf crocodiles.

[2] Unlike other crocodiles, Osteolaemus are strictly nocturnal.

Molecular data suggest that Osteolaemus tetraspis consists of two lineages that would warrant recognition as distinct species.
