Gongpoquansaurus (meaning "Gongpoquan reptile") is an extinct genus of basal hadrosauroid dinosaur that was not formally named until 2014, while the name was a nomen nudum for many years previously. It is known from IVPP V.11333, a partial skull and postcranial skeleton. It was collected in 1992 at locality IVPP 9208–21, from the Barremian Zhonggou Formation (Xinminpu Group), in Mazongshan, Gansu Province, China. The specimen was first described and named by Lü Junchang in 1997 as the third species of Probactrosaurus, Probactrosaurus mazongshanensis. Following its description, several studies found it to be less derived than the type species of Probactrosaurus in relation to Hadrosauridae. Therefore, "Gongpoquansaurus" has been suggested, yet informally, as a replacement generic name. In 2014, the genus was formally redescribed, and the describers erected Gongpoquansaurus.
