Orientalosuchina is an extinct clade of alligatoroid crocodylians from South and East Asia that lived during the Paleocene and Eocene.

The clade was named as the result of a 2019 study by Massonne et al. that included several extinct alligatoroid taxa from Asia and found that they were all closely related and together formed a monophyletic clade as basal members of Alligatoroidea, as shown in the cladogram below:^[1]

Alligatoroidea	Diplocynodontinae† Globidonta Leidyosuchus† Deinosuchus† Navajosuchus† Ceratosuchus† Stangerochampsa† Brachychampsa sealeyi† Brachychampsa montana† Orientalosuchina† Eoalligator† Jiangxisuchus† Protoalligator† Orientalosuchus† Krabisuchus† Alligatoridae Alligatorinae Caimaninae

Some studies have disputed this placement of Jiangxisuchus within Orientalosuchina as an alligatoroid, instead recovering Jiangxisuchus as a basal member of Crocodyloidea.^[2][3]
