The Villa Farnese, also known as Villa Caprarola, is a pentagonal mansion in the town of Caprarola in the province of Viterbo, Northern Lazio, Italy, approximately 50 kilometres (31 mi) north-west of Rome, originally commissioned and owned by the House of Farnese. A property of the Republic of Italy, Villa Farnese is run by the Polo Museale del Lazio. This villa is not to be confused with two similarly-named properties of the family, the Palazzo Farnese and the Villa Farnesina, both in Rome.

The House of Farnese was an influential family in Renaissance Italy. The titles of Duke of Parma and Piacenza and Duke of Castro were held by various members of the family.
