Gordiidae is a family of parasitic horsehair worms belonging to the order Gordioidea.

These horsehair worms are characterized by a post-cloacal crescent located at the base of the two tail lobes.

The genera are distinguished by the distinctly pointed tips on male Acutogordius tail lobes in comparison with Gordius.

[2] Recorded hosts are usually Polyneopteran insects such as Orthoptera and Mantodea.
