Tadzhikosuchus is an extinct genus of alligatoroid crocodilian from the Late Cretaceous of Tajikistan. To date it is mostly known from partial dentaries that show it to have been very similar to Diplocynodon. The two are differentiated by subtle differences in tooth position and tooth socket shape, and by differences in stratigraphy (Diplocynodon is known from the Paleogene, making it younger). Three species have been named: the type species T. macrodentis, described by Efimov in 1982 from the lower Santonian-age Upper Cretaceous Yalovach Svita of Kansai, Tajikistan, in the Fergana Basin of Tajikistan; T. neutralis from the same location, by Efimov in 1988; and T. kizylkumensis from Turonian-age rocks of the Upper Cretaceous Bissekty Formation of Dzharakhuduk, Uzbekistan, by Nesov and coll
