Theobald of Marly (French: Saint Thibaut, Thibault, Thiébaut; c. 1200 – 8 December 1247) was a French abbot and saint. He was born at the castle of Marly, Montmorency, and was trained as a knight. He served as a knight at the court of Philip Augustus, though he later entered the Cistercian monastery of Vaux-de-Cernay in 1220. He was elected prior in 1230 and ninth abbot in 1235.
