Lysimachus of Telmessos (Ancient Greek: Λυσίμαχος Τελμησσεύς, romanized: Lysimachos Telmēsseus, flourished 3rd century BC), also known as Lysimachus II was a Greek Prince from Asia Minor who served as a Ptolemaic Client King under the Ptolemaic dynasty of Ancient Egypt.
Lysimachus was the first-born son and heir of Ptolemy I Epigone by an unnamed Greek aristocratic mother and had a younger brother called Epigonos of Telmessos.
[6] His paternal grandmother was Arsinoe II, a Ptolemaic Greek Macedonian Princess who married his paternal grandmother as his third wife[7] who later married her full-blooded brother Ptolemy II Philadelphus as her third husband[8] and through marriage became Queen of the Ptolemaic Kingdom.
[19] At an unknown date during his reign, Lysimachus and his family were enjoying excellent cordial relations with the Seleucid monarch Antiochus III the Great.
[21] When Lysimachus died, he was succeeded by Ptolemy II of Telmessos, his son and successor by an unnamed Greek woman.
