Arpitania (Arpitan and Italian: Arpitania, French: Arpitanie) is a term which denotes the purported ethnic or cultural unity of the Western Alps, represented by speakers of Franco-Provençal (termed Arpitan).
"Arpitania" roughly corresponds to the historical County of Savoy and its successor state the Duchy of Savoy:
- France (Ain, Rhône, Savoie, Haute-Savoie, a big part of the Isère department, southern Franche-Comté). The northwestern salient (roughly a strip between Mâcon and Roanne) is seen linguistically transitional between Arpitan, Occitan, and other Oïl languages.[citation needed]
- Italy (Aosta Valley, parts of Piedmont, Faeto and Celle di San Vito in the Province of Foggia, in Apulia)
- Switzerland (Romandy, excluding the northern and western parts of Jura)
