Roussillon (French pronunciation: ​[ʁu.siˈjɔ̃]; Catalan: Rosselló, IPA: [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 French Catalonia or Northern Catalonia, the latter used by Catalan-speakers.
