Fenouillèdes (Occitan: Fenolhedés/Fenolheda, Catalan: Fenolledès/Fenolleda), is a French comarca and a traditional Occitan-speaking area in the département of Pyrénées-Orientales. The capital of the comarca is Saint-Paul-de-Fenouillet (Sant Pau de Fenolhet).
Fenolheda has been part of France since the Treaty of Corbeil of 1258. In 1790, during the French Revolution, it was incorporated in a newly created département along with the Roussillon comarques.
