Phạm Thận Duật (, 1825–1885) was a high-ranking mandarin serving in the Nguyễn dynasty of Vietnam. He and Tôn Thất Phan, representing emperor Tự Đức's court, signed the Treaty of Huế with France. He participated in the anti-colonial Cần Vương resistance and died while being sent to exile in Tahiti by the French. Knowledge of his role in the resistance was hidden or lost for many decades after his death; he was thought to have been a French collaborator for having signed the treaty. He was also a celebrated historian who was in charge of the National History Institute () and the Imperial College (). He was the final editor of The Imperially Ordered Annotated Text Completely Reflecting the History of Vietnam, a Chinese-language history of Vietnam commissioned by the emperor Tự Đức, and the mentor of future emperors Dục Đức and Đồng Khánh.

Four years later, he returned home to study under scholar Phạm Đức Diệu in Yên Mô district who later became his father-in-law.
