Mirepoix Cathedral 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. Construction continued, with interruptions, over the next six centuries. The cathedral was restored in 1858 and 1859 by Prosper Mérimée, and Eugène Viollet-le-Duc.
The cathedral has the second widest Gothic arch in Europe, after that of the Girona Cathedral in Catalonia, Spain.
