Lukousaurus is an extinct genus of archosauromorph based on most of a small snout, displaying distinctive lacrimal horns, found in the Early Jurassic lower Lufeng Formation of Yunnan, China. It was described by Chung Chien Young in 1940.

Lukousaurus was originally tentatively classified as a theropod dinosaur, allied with ceratosaurs or coelurosaurs, though other researchers have reinforced non-dinosaurian affinities, possibly related to suchians. Its skull is rather robust for its size, though the teeth were initially described as typically theropodan.
