Elne (French: [ɛln]; Catalan:Elna [ˈɛlnə], locally: [ˈ(j)elnə]) is a commune in the Pyrénées-Orientales department in southern France.

It lies in the former province of Roussillon, of which it was the first capital, being later replaced by Perpignan. Its inhabitants are still called Illibériens in reference to the city's Iberian name, Illiberis, one that it shared with the Illiberis that became Granada, Spain.
