Paralligator is an extinct genus of neosuchian crocodylomorph that lived during the Late Cretaceous (Cenomanian-Maastrichtian) period in what is now the Bayan Shireh and Nemegt formations of Mongolia, approximately 96 million to 70 million years ago. P. gradilifrons reached up to 4 m in length.

Misassigned species

"Paralligator" sungaricus, described from the Early Cretaceous Nenjiang Formation of Jilin Province, China, is based on postcranial remains consisting of a few presacral vertebrae, dorsal osteoderms, a partial left femur, and the proximal part of a left tibia and fibula. However, the type material is too fragmentary to be considered diagnostic, and the species is a nomen dubium. Turner (2015) also referred P. ancestralis a junior subjective synonym of P. gradilifrons.
