The State Museum of Natural History Stuttgart abbreviated SMNS, is one of the two state of Baden-Württemberg's natural history museums. Together with the State Museum of Natural History Karlsruhe (Staatliches Museum für Naturkunde Karlsruhe) it is one of the most important repositories for state-owned natural history collections.
Exhibitions are shown in two buildings, both situated in the Rosenstein park in Stuttgart: the Löwentor Museum (German: Museum am Löwentor) houses the paleontology and geology exhibitions, while the Museum Rosenstein in Rosenstein Palace focuses on biology and natural history. Every year, the SMNS is visited by about 110,000 people.
