Roussillon (/ˈruːsɪjɒn/ or /ˌruːsiːˈjoʊn/; French: [ʁu.si.jɔ̃]; Catalan: Rosselló [rusəˈʎo]) is one of the historical counties of the former Principality of Catalonia, corresponding roughly to the present-day southern French département of Pyrénées-Orientales (Eastern Pyrenees). It may also refer to Northern Catalonia or French Catalonia, the first used by Catalan-speakers and the second used by French-speakers.
