Mirepoix Cathedral (French: Cathédrale Saint-Maurice de Mirepoix) is a Roman Catholic church located in the southwestern town of Mirepoix, Ariège, France.

The foundation stone was laid by Jean de Lévis on 6 May 1298.

The cathedral was restored in 1858 and 1859 by Prosper Mérimée, and Eugène Viollet-le-Duc.

The diocese, created in 1317, was abolished under the civil constitution of the clergy in 1790, and confirmed under the Concordat of 1801 and the territory divided between the Diocese of Carcassonne and the Archdiocese of Toulouse.
