Học phi was a wife of Emperor Tự Đức of the Nguyễn Dynasty of Vietnam. She is best known for her involvement in palace intrigues following her husband's death.
She had an affair with Nguyễn Văn Tường, a regent that Tự Đức had appointed to guide his successors. Tường and Hoc Phi were caught together by Emperor Kien Phuc, who vowed to kill them. However, on the same night, Hoc Phi slipped poison into Kien Phuc's medicine, resulting in the emperor's death.
