 Sanjuansaurus ("San Juan Province lizard") is a genus of herrerasaurid dinosaur from the Late Triassic-age Ischigualasto Formation of northwestern Argentina. It is known from and based on an associated and partially articulated partial skeleton (PVSJ 605) consisting of a jaw fragment, most of the vertebral column from the axis to the anterior tail, the shoulder blades, an ulna, part of the pelvis, most of the long bones of the legs, and a few other bones. PVSJ 605 was found in the Cancha de Bocas Member near the base of the Ischigualasto Formation, in Ischigualasto Provincial Park in San Juan. This horizon dates to approximately 231.4 Ma, during the late Carnian Stage of the Late Triassic.

 Sanjuansaurus was named and described in 2010 by Oscar Alcober and Ricardo Martinez. The type species is S. gordilloi after Raul Gordillo, the head fossil preparator and artist of the San Juan Museum. Sanjuansaurus was a contemporary of other early dinosaurs including Chromogisaurus, Eoraptor, Herrerasaurus, and Panphagia. It was comparable in size to a medium-sized Herrerasaurus, with a thigh bone length of 395 millimetres (15.6 in). Alcober and Martinez performed a phylogenetic analysis and found Sanjuansaurus to be a herrerasaurid.
