Sang-nu (Korean: 상루; Hanja: 尙婁; died 294) was the prime minister of Goguryeo during the reign of King Seocheon, and the son of previous Prime Minister Eum-u.
Sang-nu, like his father, was from the Biryu-Bu of Goguryeo.
His last name and ancestry are also unknown, but it is known that he and his father possessed a considerable amount of power over the nobles.
This lack of mention in historical records may signify that prime minister Sang-nu was an excellent government official, or an incompetent one.
Sang-nu died in the year 294, during the 3rd year of the reign of King Bongsang and was succeeded by Chang Jo-ri.
