Intef III is a Pharaoh in Egypt of the Eleventh Dynasty during the First Intermediate Period.

His Horus name is Nakjtnebtepnefer, which translates to "Horus, the victorious one, Lord of the good beginning".

He is buried in a saff-tomb at el-Tarif (Thebes), and little is known about his deeds.

Intef successfully defended the territory that Intef II had won and held territory as far as the seventeenth nome of Upper Egypt.

He restored a ruined tomb of a deified prince named Hekayeb at Aswan.

After a short and peaceful 8 year reign, he was succeeded by his son Mentuhotep II.

Intef III was buried in a saff (row) tomb in el Tarif (near Thebes) next to Intef I and Intef II, and near Deir el-Bahri (the site of Montuhotep II's Mortuary Temple).

Intef III's grandson was Mentuhotep III and Intef had a daughter Neferu who married her brother.
