Antiquities Minister Mohamed Ibrahim said that the tomb belongs to a guard of the army archives and royal messenger to foreign countries.
He said the Cairo University Faculty of Archaeology's discovery at Saqqara adds "a chapter to our knowledge about the history of Saqqara."
Ola el-Egeizy of Cairo University said the tomb contains "very nice inscriptions" of the funerary procession and the afterlife of the deceased.
The tomb was found near another one dating back to the same period belonging to the head of the army that was discovered in the previous excavation season.
Saqqara was the necropolis for the ancient Egyptian city of Memphis and site of the oldest known pyramid in Egypt.
Egypt's vital tourism industry has suffered in the wake of the 2011 uprising that toppled autocratic leader Hosni Mubarak.
