Rudamun is the final pharaoh of the Twenty-third dynasty of Ancient Egypt.

His titulary simply reads as Usermaatre Setepenamun, Rudamun Meryamun, and excludes the Si-Ese or Netjer-Heqawaset epithets employed by his father and brother.

He was the younger son of Osorkon III, and the brother of Takelot III.

He is a poorly attested pharaoh of this dynasty according to Kenneth Kitchen's seminal book on The Third Intermediate Period of Egypt.

Kitchen credits him with a brief reign of about two to three years due to the few contemporary documents known for him.

These include a small amount of decorative work done on the Temple of Osiris Heqadjet, several stone blocks from Medinet Habu, and a vase.

In recent years, two fragments of a faience statuette bearing Rudamun's name from Hermopolis have been discovered.

This recent discovery suggests that Radamun managed to preserve the unity of his father's large kingdom in Upper Egypt ranging from at least Herakleopolis Magna to Thebes during his brief reign.
