Sekhemkhet is a Pharaoh in Egypt during the Third dynasty.

According to the Manethonian tradition, a king known as Tyris (which may be compared to the Turin Canon's "Djoser-ti") reigned for a relatively brief period of seven years, and modern scholars believe Djoserty and Sekhemkhet are the same person.

While the Turin Canon gives Sekhemkhet a reign of 6 years, Toby Wilkinson's reconstruction of the Dynasty 5 Palermo Stone Annal document assigns a reign of 7 years to this king based on the number of year register preserved for him in Cairo Fragment One, register V. Wilkinson states that "this figure is fairly certain, since the [king's] titulary begins immediately after the dividing line marking the change of reign."

Hence, the Manethonian tradition appears to be correct.

His reign is thought to have been from about 2648 BCE until 2640 BCE.

Sekhemkhet's name means "Powerful in Body."

Sekhemkhet's wife may have been Djeseretnebti, but this name appears without any quee´s title, and Egyptologists dispute the true meaning and reading of this name.

The name has alternatively been read as Djeser-Ti and identified with the cartouche-name of the pharaoh Djeser-Teti of the Abydos King List.
