Cleopatra V (; died or ) was a Ptolemaic Queen of Egypt. She is the only surely attested wife of Ptolemy XII. Her only known child is Berenice IV, but she was also probably the mother of Cleopatra VII. It is unclear if she died around the time of Cleopatra VII's birth in 69 BC, or if it was her or a daughter named Cleopatra VI who co-ruled Ptolemaic Egypt with Berenice IV in 58–57 BC during the political exile of Ptolemy XII to Rome. No written records about Cleopatra V exist after 57 BC and two years later Berenice IV was overthrown by Ptolemy XII, his throne restored with Roman military aid. Descent and marriage Because of the poor body of source material Cleopatra V is a very obscure member of the Ptolemaic dynasty. Only a few ascertained facts about her are known. Many aspects of her life are the subject of controversial theories. In all known ancient sources she is given the byname Tryphaena. She may have borne this name before accession to the throne when she assumed the traditional royal name Cleopatra. In some modern specialist literature Cleopatra Tryphaena, wife of Ptolemy XII, is referred to as Cleopatra VI. The historian of classical antiquity Werner Huß refers to her as Cleopatra VII Tryphaena. The parentage of Cleopatra V is not recorded. She may have been a legitimate or illegitimate daughter of Ptolemy IX or the legitimate daughter of Ptolemy X. It is mentioned that in 88 BC, Ptolemy X Alexander fled Egypt with his wife Berenice III and his daughter. Cleopatra Tryphaena might be this unnamed daughter. Cleopatra V is first mentioned in 79 BC in two papyri. One of these papyri dates from January 17, 79 BC. In that year she married Ptolemy XII, king of Egypt. They received divine worship as theoí Philopátores kai Philádelphoi (father-, brother- and sister-loving gods). Cleopatra’s Egyptian titles, found primarily at Edfu and Philae, include Daughter of Re, Female Ruler, and Mistress of Two Lands. Death and identity It is unclear how long Cleopatra V lived, and with which mentions of Cleopatra Tryphaena in the historical record she should be identified, as the numbering used to distinguish the Ptolemies is a modern invention. Cleopatra Tryphaena V vanished around the time Cleopatra VII was born (69 BC): her name begins to disappear from monuments and papyri, and there is a papyrus
