Lake Nemi (Italian: Lago di Nemi, Latin: Nemorensis Lacus, also called Diana's Mirror, Latin: Speculum Dianae) is a small circular volcanic lake in the Alban Hills 30 km (19 mi) south of Rome in the Lazio region of Italy. It takes its name from Nemi, the largest town in the area, which overlooks it from a height.

It was formed in an ancient volcanic crater created at least 36,000 years ago.

The lake is famous for its great sunken Roman ships built under Caligula.
