Saint-Antoine-l'Abbaye, also Saint-Antoine-en-Viennois, is a commune in the Isère department in south-eastern France. Formerly known as La-Motte-Saint-Didier, it was renamed after becoming the home of the relics of Saint Anthony the Great in the 11th century, and shortly afterwards of the original house of the Hospital Brothers of St. Anthony, founded here in 1095 as the result of miraculous cures from St. Anthony's Fire ascribed to the relics.
