Ptolemy Neos Dionysos Theos Philopator Theos Philadelphos (117–51 BCE; Greek New Dionysus, God Beloved of his Father, God Beloved of his Brother), more commonly known as "Auletes" (the Flutist) or "Nothos" (the Bastard), is an Egyptian king of Macedonian descent.

Auletes means pipes-player, referring to the king's love of playing the pipes.

Ptolemy, who reigns during the period of Hellenism, is assumed to have been an illegitimate son of Ptolemy IX Soter, perhaps by an Egyptian woman, but he is also possibly the Son of Ptolemy XI and Cleopatra IV.
