Intef III was the third pharaoh of the Eleventh Dynasty of Egypt during the late First Intermediate Period in the 21st century BC, at a time when Egypt was divided in two kingdoms. The son of his predecessor Intef II and father of his successor Mentuhotep II, Intef III reigned for 8 years over Upper Egypt and extended his domain North against the 10th Dynasty state, perhaps as far north as the 17th nome. He undertook some building activity on Elephantine. Intef III is buried in a large saff tomb at El-Tarif known as Saff el-Barqa.
