Placerias (meaning "broad body") is an extinct genus of dicynodonts that lived during the late Carnian age of the Triassic Period (221-210 million years ago). Placerias belongs to a group of dicynodonts called Kannemeyeriiformes, which was the last known group of dicynodonts before most of dicynodonts became extinct at the end of the Triassic.

As a Triassic reptile, Placerias was one of the largest plant eaters in its environment. It is part of a great infraorder of creatures known as dicynodonts. It had a barrel-like body, pillar-like legs and a powerful and compact neck.
