Fregellae was an ancient town of Latium adiectum, situated on the Via Latina between Aquinum (modern Aquino) and Frusino (now Frosinone), in central Italy, near the left branch of the Liris.

[3][4] (A messenger from the city caused panic throughout Rome until word arrived that a Roman army was en route from Capua.

[5] Fregellae appears to have been a very important and flourishing place owing to its command of the crossing of the Liris and to its position in a fertile territory.

[6] The following year, Fregellae's place was taken by the colony of Fabrateria Nova, 3 miles (4.8 km) to the southeast on the opposite bank of the Liris.

Under the empire, Fregellae is recorded as a small village and a post station at modern Ceprano called Fregellanum is mentioned in the itineraries.
