Ciociaria is the name of a traditional region of Central Italy without a defined border nor historical identity. The name was adopted by a fascist movement of Frosinone as an ethnical denomination for the province of Frosinone, when it was created in 1927. In the Middle Ages, this region was referred to as Campagna. The local dialect, now known as ciociaro, was earlier referred to as campanino. In more recent times, the term Campagna Romana, or Roman Campagna, a favorite subject of countless painters from all over Europe, has referred to the adjoining region to the north of Ciociaria, but part of the Province of Rome.
The name appears to be derived from the ciocia (plural cioce), the traditional footwear still worn by a few sheep and cattle herders in the Central Apennines.
Ciociaria is also the name of asteroid 21799 (see List of named asteroids (A-E), List of asteroids (21001-22000), and Meanings of asteroid names (21001-22000)) .
