Magyarosaurus ("Hungarian lizard") is a genus of dwarf sauropod dinosaur from late Cretaceous Period (early to late Maastrichtian) in today's Transylvania. It is one of the smallest-known adult sauropods, measuring less than long and weighing less than . The type and only species is Magyarosaurus dacus. It has been found to be a close relative of Rapetosaurus in the family Saltasauridae in the sauropod clade Titanosauria in a 2005 study.

==Discovery== thumb|left|Magyarosaurus sp. scapula Remains belonging to at least ten individuals have been recovered since 1895 from the Hunedoara region (Sânpetru Formation) in the area which was, at the time of their discovery, Hungary, but is now western Romania. Initially they were named Titanosaurus dacus, the specific name referring to the Dacians (who had lived in that place about 2000 years ago), by Baron Nopcsa in 1915. In 1932, Friedrich von Huene reassigned this taxon to a new genus, Magyarosaurus, and he also named two other species within the genus: M. hungaricus and M. transsylvanicus. However, M. transsylvanicus represents a chimera and some material belongs to M. dacus, while M. hungaricus is now reassigned to a distinct genus Petrustitan with some previously referred material now being the specimens of another genus Uriash.
