Etymology Tête cornue errante (du Latin ''vagus'', "errer" ou "vagabonder" et du Grec ''ceratops'', "face cornue").

Vagaceratops is a genus of chasmosaurine ceratopsid dinosaur which lived during the Late Cretaceous period in what is now Alberta. Its fossils have been recovered from the Upper Dinosaur Park Formation. It is sometimes included in the genus Chasmosaurus as Chasmosaurus irvinensis instead of being recognized as its own genus.
