Auxerre Cathedral, also known as Cathedral of Saint Étienne d'Auxerre, is a Roman Catholic cathedral located in Auxerre, France. It is dedicated to Saint Stephen, the first Christian martyr.

The cathedral is a fine example of Gothic architecture, built between the 13th and 16th centuries. The façade features three portals with sculpted tympanums and a rose window. The interior has a nave and two aisles with vaulted ceilings, a transept and an apse with ambulatory and radiating chapels. The choir stalls are decorated with carvings of biblical scenes and allegories.

One of the most famous works of art in the cathedral is the magnificent stained glass windows. The oldest set dates from the 13th century and depicts scenes from the Old Testament. The other windows are from the 14th, 15th and 16th centuries and illustrate scenes from the life of Christ and various saints. The windows are considered to be some of the finest examples of medieval stained glass in France.
