Chameria is a historical region along the coast of the Ionian Sea in southwestern Albania and northwestern Greece, traditionally associated with the Albanian ethnic subgroup of the Chams. For a brief period (1909-1912), three kazas were combined by the Ottomans into an administrative district called Çamlik sancak. During the interwar period, the toponym was in common use and the official name of the area above the Acheron river in all Greek state documents. The term is used today mostly by Albanians and it is obsolete in Greek, surviving in some old folk songs. Most of what is called Chameria is divided between parts of the Greek regional units of Thesprotia, Preveza, and Ioannina ; and the municipality of Konispol at the southernmost extremity of Albania. Apart from geographic and ethnographic usages, in contemporary times within Albania the toponym has also acquired irredentist connotations.
