Ramesses IX (also written Ramses) (originally named Amon-her-khepshef Khaemwaset) (ruled 1129 – 1111 BC) was the eighth king of the Twentieth dynasty of Egypt. He was the third longest serving king of this Dynasty after Ramesses III and Ramesses XI. He is now believed to have assumed the throne on I Akhet day 21 based on evidence presented by Jürgen von Beckerath in a 1984 GM article. According to Papyrus Turin 1932+1939, Ramesses IX enjoyed a reign of 18 Years and 4 months and died in his 19th Year in the first month of Peret between day 17 and 27. His throne name, Neferkare Setepenre, means "Beautiful Is The Soul of Re, Chosen of Re." Ramesses IX is believed to be the son of Mentuherkhepeshef, a son of Ramesses III since Montuherkhopshef's wife, the lady Takhat bears the prominent title of King's Mother on the walls of tomb KV10 which she usurped and reused in the late 20th dynasty; no other 20th dynasty king is known to have had a mother with this name. Ramesses IX was, therefore, probably a grandson of Ramesses III.
