Krabisuchus is an extinct genus of alligatorine crocodylian that existed in what is now Thailand during the Eocene. It was first named by paleontologists Jeremy A. Martin and Komsorn Lauprasert in 2010, and the type species is K. siamogallicus. Fossils have been found from the Krabi Basin of southern Thailand and include mostly cranial and mandibular elements as well as some postcranial remains. Krabisuchus is currently the most well known primitive alligatorine from Asia; previously, these animals were only represented in Asia by a few fragmentary remains from China. The fossil record of alligatorines is much more extensive in Europe and North America, where most taxa have been described.
