Peloroplites (from Greek pelor "monster", and hoplites, "armoured soldier") is a genus of nodosaurid armored dinosaur from Lower Cretaceous rocks of Utah. It is known from a partial skull and partial postcranial remains from the base of the Mussentuchit Member of the Cedar Mountain Formation, deposited during the Albian-Cenomanian boundary, about 104.46 to 98.37 million years ago, and was found in Emery County, Utah. It was named in 2008 by Kenneth Carpenter and colleagues.
Peloroplites was about 5 to 5.5 meters (16 to 18 ft) long, comparable to its approximate contemporary Sauropelta. It is one of the largest known nodosaurids, and came from a time when ankylosaurians in general were attaining large sizes.
