Borçka (Laz: ბორჩხა/Borçxa; Georgian: ბორჩხა/Borchkha, also ფორჩხა/Porchkha; archaic Greek: Σωτηρόπολης/Soteropolis) is a town and district of Artvin Province in the Black Sea region of Turkey, on the border with Georgia.

Borçka is reached by a winding road up from the Black Sea coast, alongside the Çoruh River (Nigali valley). There is a medieval stone arched bridge across the river just west of the town.
