Terminonaris is a genus of extinct pholidosaurid crocodyliforms that lived in the Late Cretaceous (Cenomanian and Turonian[1][2]). Its remains are known from North America. Originally known under the generic name Teleorhinus, it was once believed to be a teleosaurid (a family of marine gavial-like thalattosuchians).

Terminonaris was an enormous predator, reaching a length of 6 m (20 ft).[1]
