Chanaresuchus is an extinct genus of proterochampsid archosauromorph. It was of modest size for a proterochampsid, being on average just over a meter in length. Fossils have been found from the Chañares Formation in La Rioja Provence, Argentina, dating back to the Anisian stage of the early Middle Triassic. Chanaresuchus appears to be one of the most common "thecodont" archosaurs from the formation due to the abundance of specimens referred to the genus. Much of the material has been found by the La Plata-Harvard expedition of 1964-65.
