Watsonisuchus is an extinct genus of temnospondyl from the Early Triassic of Australia, Madagascar, and South Africa.^[1] It was up to 122 cm long and had a robust skull of 24 cm in length.^[2]

Three or four species are known:^[3] W. magnus (the type species), W. aliciae (which may instead belong to Warrenisuchus), W. gunganj, and W. rewanensis.
