Odonterpeton is an extinct genus of "microsaur" (small reptiles or reptile-like amphibians) from the Late Carboniferous of Ohio, containing the lone species Odonterpeton triangulare. It is known from a single partial skeleton preserving the skull, forelimbs, and the front part of the torso. The specimen was found in the abandoned Diamond Coal Mine of Linton, Ohio, a fossiliferous coal deposit dated to the late Moscovian stage (Westphalian D), about 310 million years ago.

Odonterpeton was very small even among microsaurs, and its skeletal anatomy has been compared to aquatic salamanders such as amphiuma. Its habitat was a tropical river and delta environment bustling with fish, amphibians, and rare early reptiles. The three-fingered forelimbs are tiny, and hindlimb evidence is unclear. Odonterpeton is the sister taxon to Joermungandr bolti (a scaly four-limbed microsaur from the Mazon Creek fossil beds of Illinois), and together they make up the family Odonterpetidae.
