Engaeus is a genus of freshwater crayfish found in Australia, the burrowing crayfishes. Fifteen of the 35 species in the genus occur in Tasmania, where they are known as the Tasmanian land crayfishes. The behaviour of these crayfish is notable as they live in burrows and construct large "chimneys" at the opening.
