Sinankylosaurus (meaning "Chinese fused lizard") is a dubious dinosaur genus known from the Late Cretaceous Hongtuya Formation of China. The genus contains a single species, Sinankylosaurus zhuchengensis, known from a partial right ilium (a pelvic bone). This specimen was originally described as belonging to an ankylosaur, although later research has disputed this identification, noting the lack of anatomical characters uniting Sinankylosaurus with this group.

==Discovery and classification== Beginning in 1964, after the discovery of a hadrosaur tibia that would later be assigned to Shantungosaurus, researchers began conducting paleontological fieldwork in the Wangshi Group in Shandong Province, China. Large-scale excavations conducted in 1988 and 2008 in three localities of this region yielded thousands of dinosaur remains, representing hadrosaurids, ceratopsians, sauropods, tyrannosaurids, and oviraptorosaurs. Together, these animals represent a faunal assemblage comparable to those in Late Cretaceous North America. Among the material collected was a nearly complete right , housed in the Zhucheng Dinosaur Research Center, where it is accessioned as specimen ZJZ-183. This bone was found in outcrops of the Hongtuya Formation near Zangjiazhuang Village in Zhucheng of Shandong Province, China.
