Ceccano is a town and comune in the province of Frosinone, Lazio, central Italy, in the Latin Valley.

The town had its origins as an ancient Volscian citadel that surrendered to the Romans in 330 BC (424 Ab Urbe Condita).

From 900 to 1450, it was ruled by the local Counts of Ceccano – most likely of German origin; later their territories were assigned to Rodrigo Borgia by Pope Alexander VI and then to the Colonna family.

From 3 November 1943 and 31 May 1944, during World War II, the town suffered 38 air attacks from Allied forces despite having no strategical importance.

During excavations for the construction of the TAV high speed railroad, remains of a large Roman villa have been discovered.
