Roussillon (UK: /ˈrsɪjɒn/ ROO-si-yon,[1] US: /ˌrsˈjn/ ROO-see-YOHN,[2] French: [ʁusijɔ̃]; Catalan: Rosselló [rusəˈʎo]; Occitan: Rosselhon [ruseˈʎu]) is a historical province of France that largely corresponded to the County of Roussillon and part of the County of Cerdagne of the former Principality of Catalonia. It is part of the region of Northern Catalonia[lower-alpha 1] or French Catalonia (the former used by Catalan-speakers and the latter used by French-speakers), corresponding roughly to the present-day southern French département of Pyrénées-Orientales (with Roussillon, Conflent, and Fenouillèdes) in Languedoc-Roussillon.
