Henry of Marcy, or Henri de Marsiac, (c. 1136 –1 January 1189) was a Cistercian abbot, first of Hautecombe in Savoy (1160–1177), and then of Clairvaux, from 1177 until 1179. He was created Cardinal Bishop of Albano by Pope Alexander III at the Third Lateran Council in 1179. Henry was an important figure in the fight against the late twelfth-century movements of Catharism and Waldensianism and was prominent at the Third Lateran Council. He supported the use of force to suppress heresy and a strong alliance between secular and ecclesiastic authority in the use of force.
