Wangosaurus is an extinct genus of basal pistosauroid known from the Middle Triassic (late Ladinian stage) Falang Formation of Xingyi in Guizhou Province, southwestern China. It contains a single species, Wangosaurus brevirostris, first described and named by Le-Tian Ma, Da-Yong Jiang, Olivier Rieppel, Ryosuke Motani and Andrea Tintori in 2015. The specific name brevirostris comes from Greek for "short snout". It is known solely from its holotype, a nearly complete and articulated skeleton missing only the rear part of its tail.
