The Ichthyostegidae is a small family of extinct labyrinthodont amphibian from the Devonian. All members of the family were relatively large animals with primitively polydactyl, paddle-like feet.

Two genera are assigned to the family: the nominal Ichthyostega from Greenland and Hynerpeton found in Pennsylvania, U.S.A. Bout appear to have been fairly capable on dry land, when compared with the contemporary Acanthostegids.
