The Torre Valley dialect or Ter Valley dialect (tersko narečje, terščina) is the westernmost and the most Romanized Slovene dialect and one of its most archaic and typologically interesting dialects. It is spoken mostly in the Torre Valley in the Province of Udine in Italy, in the northern part of the historical region known as Venetian Slovenia, and in some villages in western Slovenia. It belongs to the Littoral dialect group. Historically, it included the village of Pers (Slovene: Breg or Brieh), the westernmost ethnically Slovene village.
