The Cathedral of St Vincent de Paul is a Roman Catholic cathedral in Tunis.
It is named in honour of Saint Vincent de Paul, a priest sold into slavery in Tunis, who after being freed took an interest in helping Christian slaves in the area. The cathedral is the headquarters of the Diocese of Tunis. It is situated in the Place de l'Indépendence in the Ville Nouvelle, a crossroads between Avenue Habib Bourguiba and Avenue de France, opposite the French embassy.
The church was built in a mixture of styles, including Moorish, Gothic, and Neo-Byzantine.
