Dorateuthis is a genus of cephalopod from the Upper Santonian shale of Late Cretaceous Lebanon. Though traditionally regarded as a plesioteuthidid squid, it may instead be a member of the suborder Prototeuthina, the earliest-diverging branch of Octopoda. Dorateuthis was small, with a mantle length of 5–40 cm (2.0–15.7 in). The contents of its digestive system suggest that it may have fed on small fishes and been an active predator.
