Cleopatra VI Tryphaena (Greek: Κλεοπάτρα Τρύφαινα, romanized: Trýphaina, lit. 'dainty') or Cleopatra Tryphaena II (died c. 57 BC) was a queen of Ptolemaic Egypt who ruled alongside Berenice IV, who was either her sister or daughter.
Although called Cleopatra VI Tryphaena by some modern historians, she may be identical with Cleopatra V, the known mother of Berenice IV and wife of pharaoh Ptolemy XII Auletes.[2] Or Cleopatra VI could have been a daughter of Ptolemy XII Auletes and thus older sibling of Berenice IV, Cleopatra VII, Ptolemy XIII, and Ptolemy XIV. After co-ruling Egypt for a year, Cleopatra VI died of unknown causes in 57 BC, after which Ptolemy XII Auletes returned to Egypt with Roman military aid to overthrow his rival daughter Berenice IV in 55 BC.
