Kansajsuchus is a genus of extinct crocodyliform that may have been a goniopholidid mesoeucrocodylian. It is based on PIN 2399/301, a right premaxilla, one of the bones of the tip of the snout. This specimen was found in rocks of the lower Santonian-age Upper Cretaceous Yalovach Svita of Kansai, in the Fergana Basin of Tadzhikistan. Additional fossils including vertebrae and bony armor have been assigned to this genus. It would have been a large animal, estimated at up to 8 meters (26 ft) long. Kansajsuchus was described in 1975 by Mikhail Efimov. The type species is K. extensus.
