Enicocephalidae, also called unique-headed bugs and gnat bugs, are a family of around 300 species of the suborder Heteroptera.

They are typically 4 mm (0.16 in) long, and found throughout the world.

The family members can be separated from those of the Aenictopecheidae on the basis of the pronotal division into three lobes (except in the genus Alienates).

They also show polymorphism with winged males and wingless or short-winged females.
