Dongyangopelta (meaning "Dongyang shield") is an monospecific genus of nodosaurid dinosaur that lived in China during the Early to Late Cretaceous period (Albian to Cenomanian stages, 105-96 Ma) in what is now the Chaochuan Formation.

The type and only known species, Dongyangopelta yangyanensis, is known from a partial postcranial skeleton preserving osteoderms and ossified tendons.

In October 2009, a partial skeleton of an ankylosaur was discovered by Zhiwei Yang in rocks of the Chaochuan Formation, in a hillside beside the Yangyan Village southeast of the Donyang City, Zhejiang Province, China.

[1] Chen and colleagues (2013) assigned Dongyangopelta to the clade Nodosauridae, based on the femoral head being well separated from the great trochanter.

[1] Later, a phylogenetic analysis performed by Arbour and Currie (2015) recovered it within a polytomy with Sauroplites and Taohelong at the base of Nodosauridae.

[2] A similar result was replicated by Rivera-Sylva and colleagues (2018), with the only difference being the inclusion of Mymoorapelta and the exclusion of Taohelong within the polytomy.
