Lijiangosaurus is an extinct genus of nothosaurian sauropterygian reptiles known from the Middle Triassic (Anisian age) Beiya Formation of China. The genus contains a single species, Lijiangosaurus yongshengensis, known from a partial articulated skeleton including the skull. With 42 cervical vertebrae, Lijiangosaurus is characterized by its unusually elongated neck, longer than all other members of the marine reptile clade Sauropterygia except for pistosauroids (the group including the longer-necked plesiosaurs).
