Mesorhinosuchus is an extinct genus of basal phytosaur possibly known from the Early Triassic (early Olenekian stage) of Saxony-Anhalt, central-eastern Germany. It was first named by Otto Jaekel in 1910 and the type species is Mesorhinus fraasi. The generic name Mesorhinus was preoccupied by Mesorhinus piramydatus Ameghino, 1885, a macraucheniid meridiungulatan mammal. Thus, an alternative generic name, Mesorhinosuchus, was proposed by Oskar Kuhn in 1961. The genus is occasionally misspelled as Mesorhinosaurus, while Stocker and Butler (2013) recently misspelled its original generic name as Mesosuchus.
