Northern Catalonia (Catalunya Nord, in Catalan) is a term that is sometimes used, particularly in Catalan writings, to refer to the territory ceded to France by Spain through the signing of the Treaty of the Pyrenees in 1659. The area corresponds approximately to the modern French département of the Pyrénées-Orientales. The equivalent term in French, Catalogne Nord, is used nowadays, although less often than the more politically neutral Roussillon (in reference to the pre-Revolutionary province). Sometimes French Catalonia can also be used.
