Pairis Abbey is a former Cistercian monastery in Orbey in Haut-Rhin, Alsace, northeastern France. The surviving building serves today as a nursing home.
The abbey was founded in 1138 by the Count of Eguisheim.
In the 13th century, abbot Martin of Pairis preached the Fourth Crusade and then participated in the misfire of it. After taking active part in the sacking of Constantinople, Martin brought several looted relics from there to Pairis, increasing the status of the monastery considerably. The monk Gunther of Pairis wrote an account of the crusade.
The abbey was suppressed during the French Revolution.
