Paroria (Bulgarian: Парория, Greek: Παρορία) is a protected area in the Strandzha Mountains of southeastern Bulgaria.

It is known for its old-growth forests and also for being a 14th-century monastic center led by Gregory of Sinai and his disciples such as Romylos of Vidin.

Paroriais located just to the west of the villages of Zabernovo and Kalovo in Malko Tarnovo Municipality, Burgas Province (less than 30 km from the border with Turkey).

The Bulgarian emperor Ivan Alexander (reigned 1331–1371) gave refuge to Gregory of Sinai and provided funds for the construction of a monastery in Paroria, which attracted clerics from Bulgaria, Byzantium, and Serbia.

[3] Throughout the 14th century, Paroria had many bandits who regularly harassed the local monks, although imperial intervention had often helped to ameliorate the situation.
