Hanssuesia is a genus of pachycephalosaurid dinosaurs from the late Cretaceous period. It lived in what is now Alberta and Montana, and contains the single species Hanssuesia sternbergi. thumb|left|Life restoration Hanssuesia is based on a skull dome originally named Troodon sternbergi by Barnum Brown and Erich Maren Schlaikjer in 1943.

Sternberg himself, as a Stegoceras sternbergi.
The genus Hanssuesia was first named by Robert M. Sullivan in 2003. The generic name honours paleontologist Hans-Dieter Sues. The spelling variant "Hanssuessia" appeared in the publication, but the same year Sullivan chose for Hanssuesia as the valid name. Its type species is Troodon sternbergi, and the combinatio nova is Hanssuesia sternbergi.
