The abbey of Saint Mary of Arles-sur-Tech (Catalan: Santa Maria d'Arles; French: Sainte-Marie d'Arles-sur-Tech, Notre-Dame d'Arles-sur-Tech) was a Benedictine monastery in Arles-sur-Tech in the Vallespir between the ninth century and the eighteenth.
It was dedicated to Mary, mother of Jesus, and belonged to the diocese of Perpignan.
It is placed in the province of Septimania and is recorded as owing prayers for the imperial family, but not military service or taxes.
At the request of King Philip II of Spain, the abbey of Arles-sur-Tech was united with the abbey of Saint-André-de-Sorède [fr] by a bull of Pope Clement VIII dated 13 August 1592.
[1] At the start of the French Revolution in 1789, the united monastery had only six monks.
