The Monti Lepini (Italian: Lepini mountains) are a mountain range which belongs to the Anti-Apennines of the Lazio region of central Italy, between the two provinces of Latina and Rome.
The name derives probably from the Latinlapis (stone), referring to the mountains’ limestone rocks. In ancient times the area was settled by the Volsci.
