Agde Cathedral (French: Cathédrale Saint-Étienne d'Agde) is a Roman Catholic church located in Agde in the Hérault département of southern France. The cathedral is dedicated to Saint Stephen, and stands on the bank of the river Hérault.
It was formerly the seat of the Bishops of Agde, the last of whom, Charles-François-Siméon de Rouvroy de Saint-Simon de Vermandois de Sandricourt, was guillotined during the Terror. The see was not restored after the French Revolution and its parishes were added to the Diocese of Montpellier by the Concordat of 1801.
