Orpah is a woman mentioned in the Book of Ruth in the Hebrew Bible. She was from Moab and was the daughter-in-law of Naomi and wife of Kilion. After the death of her husband, Orpah and her sister-in-law Ruth wished to go to Judea with Naomi. However, Naomi persuaded Orpah to return to her people and to her gods (Ruth i. 4 et seq.).
