Gongshuilong (“Gong River dragon”) is an extinct genus of saurolophine hadrosaurid dinosaur known from the Late Cretaceous (Maastrichtian age) Lianhe Formation of China. The genus contains a single species, Gongshuilong fanwei, known from a bonebed representing the disarticulated remains of at least two individuals. Gongshuilong is a member of the group Brachylophosaurini within the Hadrosauridae, and it is the second member of this otherwise North American clade, following Wulagasaurus, found in Asia. It is also the first hadrosaurid to be named from fossils found in South China. Gongshuilong is characterized by the uniquely elongated and curved of the vertebrae at the end of the tail, forming a tall, sail-like structure.
