Escaladieu Abbey (French: l'Abbaye de l'Escaladieu) was a Cistercian abbey located in the French commune of Bonnemazon in the Hautes-Pyrénées.
In the middle of the 12th century, a group of monks under the protection of the count of Bigorre who lived at Cabadur in the Gripp valley in the modern-day Canton of Campan in Bagnères-de-Bigorre, wanted to move to a more hospitable location and therefore establish the abbey at Bonnemazon.
