Protathlitis (meaning "champion") is a genus of spinosaurid dinosaur from the Early Cretaceous (Barremian) Arcillas de Morella Formation of Castellón, Spain. The type and only species is Protathlitis cinctorrensis, known from a partial skeleton. It was a basal member of the Baryonychinae. Its discovery, as well as those of the spinosaurids Camarillasaurus, Iberospinus, Riojavenatrix, and the contemporary Vallibonavenatrix shows that the Iberian Peninsula held a diverse assemblage of spinosaurids during the Early Cretaceous.
