Pendraig (meaning "chief dragon" in Middle Welsh) is a genus of coelophysoid theropod dinosaur from South Wales.

The fossils were originally thought to belong to a "coelurosaur" (in the outdated sense of the word) and even subsequently classified as a species of "Syntarsus" (now Megapnosaurus or Coelophysis).

[4] Recently Angela Milner and Susannah Maidment rediscovered the fossils stored with some crocodile bones (likely Terrestrisuchus).

[1] Spiekman et al. recover Pendraig as a coelophysoid theropod, in a polytomy with Powellvenator, Lucianovenator, and the clade comprising "Syntarsus" kayentakatae and Coelophysidae.

[5] Other taxa known from the Pant-y-Ffynnon quarry that would have lived alongside Pendraig include the engimatic pseudosuchian Aenigmaspina, the basal crocodylomorph Terrestrisuchus, the sauropodomorphs Thecodontosaurus and Pantydraco, the rhynchocephalians Clevosaurus and Diphydontosaurus, and the gliding reptile Kuehneosaurus.
