The Pomme de Terre River (pronounced pohm de TEHR) is a 130-mile-long (210 km) tributary of the Osage River in southwestern Missouri in the United States. Via the Osage and Missouri rivers, it is part of the watershed of the Mississippi River.

Pomme de terre is French for potato, a food Indians harvested in the area. Before the French explorers, the Osage people, who were historically indigenous to the region, had called it a name meaning Big Bone River, referring to the fossils of mastodons and other ancient creatures which they found along its eroding banks.
