Orientalosuchina is an extinct clade of alligatoroid crocodylians from Southeast and East Asia that lived between Maastrichtian 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: They defined this clade as "the most inclusive clade containing Orientalosuchus naduongensis, Krabisuchus siamogallicus, Eoalligator chunyii, Jiangxisuchus nankangensis and Protoalligator huiningensis, but not Brachychampsa montana, Stangerochampsa mccabei, Leidyosuchus canadensis, Diplocynodon darwini, Bottosaurus harlani, or any species of recent Crocodylia".
Some studies have disputed this placement of Jiangxisuchus within Orientalosuchina as an alligatoroid, instead recovering Jiangxisuchus as a basal member of Crocodyloidea.
