Metjen (also read as Methen) was an ancient Egyptian high official at the transition time from 3rd Dynasty to 4th Dynasty. He is famous for his tomb inscription, which states that he worked and lived under the kings (pharaohs) Huni and Sneferu.

According to his tomb inscriptions, Metjen was a son of the high official Inpu-em-Ankh, a judge at the royal court of justice and a royal scribe. Metjen's mother was a high priestess named Neb-senet. Metjen's children were mentioned, but not named.

As a high-ranking official, Metjen bore several elite titularies:

His parents' support of his career is mentioned.

Metjen's tomb inscriptions are of the highest interest to Egyptologists and historians alike. They are the earliest known Ancient Egyptian texts detailing more than titles or instructions for offerings. Metjen was one of the first officials in high office that reported on his own professional and curatorial career. His official and honorary titles are listed in chronological order.

According to Metjen's autobiography, some high ranking titles were assigned to him by his father. He also inherited his father's titles after his death. These titles included several decrees which allowed Metjen to found his own estates and some small towns.

Metjen began his career as a royal scribe. He later became the overseer of the royal scribes and confidant to the king. He progressed to an administrator of several palatinates and royal storages. Finally, he became "the Great One of the 'Ten of Upper Egypt'" and a member of a type of privy council. The royal house gave several estates to Metjen. He founded a town called Sheret-Metjen (Egyptian: Šr.t-Mṯn) at his favorite estate.

As a sign of gratitude, Metjen donated hundreds of precious trees to other royal domains. At the peak of his career, Metjen was the mayor of several cities, the curator of the endowment estate of King Huni, and supervisor of the mortuary cult for Queen Nimaathapi.
