Horemheb or Harmhab, d. c.1303 B.C., king of ancient Egypt (c.1342 B.C.-c.1303 B.C.), founder of the XIX dynasty. A powerful noble under Ikhnaton, he seems to have been an army commander under the successors of that ruler, most notably under Tutankhamen. As king, Horemheb repaired the temples of Amon, abandoned or demolished buildings erected under Ikhnaton, and by untiring effort suppressed corruption in the government and restored prosperity to Egypt. He was succeeded by Ramses I.
