Longpont Abbey (Abbaye Notre-Dame de Longpont) was a Cistercian monastery, in present-day Longpont, Aisne, France.
It existed from 1131 to 1793, being founded by monks from the abbey of Clairvaux, at the behest of Jocelin of Soissons. There is now a hotel on the site, located in the old Cistercian inn. The roofless abbey church can be visited, along with the better-preserved buildings around the cloister. The original buildings suffered war damage in 1918.
Its monks included Petrus Cantor and John de Montmirail.
