Edmontonia is an armoured dinosaur genus from the Late Cretaceous Period. It belongs to the Nodosauridae family, which is Ankylosauria’s armoured dinosaur family. It was named after the Edmonton Formation, now known as the Horseshoe Canyon Formation in Canada, the rock unit where it was discovered.

Edmontonia was large, wide and tank-like. Its length was estimated to be approximately 6.6m (22 feet). Gregory S. Paul in 2010 considered both the main Edmontonia species E. longiceps (22 ft) to be equal length at 6 m and three tonnes respectively.

Edmontonia was small with small oval-shaped bony plates along its head and back, and had many sharp spikes running its length. Each side had four large spikes that protruded from its shoulders. The second was subspun in E. rugosidens specimens. The skull was pear-shaped when seen from the top. Three large, keeled plates formed halfrings that protected its neck and shoulders.
