Thutmose III, sometimes called Thutmose the Great, was the sixth pharaoh of the 18th Dynasty. Officially he ruled Egypt from 28 April 1479 BC until 11 March 1425 BC, commencing with his coronation at the age of two and concluding with his death, aged fifty-six; however, during the first 22 years of his reign, he was coregent with his stepmother and aunt, Hatshepsut, who was named the pharaoh. While he was shown first on surviving monuments, both were assigned the usual royal names and insignia and neither is given any obvious seniority over the other. Thutmose served as the head of Hatshepsut's armies. During the final two years of his reign, he appointed his son and successor, Amenhotep II, as his junior co-regent. His firstborn son and heir to the throne, Amenemhat, predeceased Thutmose III.

Pharaoh is the vernacular term often used for the monarchs of ancient Egypt, who ruled from the First Dynasty until the annexation of Egypt by the Roman Republic in 30 BCE. However, regardless of gender, "king" was the term used most frequently by the ancient Egyptians for their monarchs through the middle of the Eighteenth Dynasty during the New Kingdom. The earliest confirmed instances of "pharaoh" used contemporaneously for a ruler were a letter to Akhenaten or an inscription possibly referring to Thutmose III.
