The Church of Saint-Séverin (French: Eglise Saint-Séverin) is a church in the Latin Quarter of Paris, located on the lively tourist street Rue Saint-Séverin. It is one of the oldest churches that remains standing on the Left Bank, and it continues in use as a place of worship.
The church is dedicated to Séverin, who is said to have been a hermit who lived there and prayed in a small rudimentary oratory. After Séverin's death, a basilica was constructed on the spot. This was destroyed by the Vikings, and the current church building was started in the 11th century, though its major features are late Gothic and date from the 15th century.
