Epigonus of Telmessos (Ancient Greek: Επίγονος Τελμησσεύς, romanized: Epigonos Telmēsseus, flourished 3rd century BC) was a Greek prince from Asia Minor.
Epigonus may have been a second-born son to Ptolemy I Epigone and younger brother Lysimachus of Telmessos, but this is disputed.
He was born at an unknown date either in his father’s co-regency of the Ptolemaic Kingdom with Ptolemy II in Alexandria Egypt which was from 267 BC until 259 BC[8] or when his father was the first Ptolemaic client king of Telmessos in Lycia.
[12][13] As his family likely had relative autonomy from Ptolemaic control increased[14] and Ptolemaic power declined rapidly and dramatically outside of Egypt after the death of Ptolemy III Euergetes in 222 BC, probably Epigonus with his family had the motive and opportunity for divorcing themselves from Ptolemaic suzerainty.
[15] At an unknown date, Epigonus with his brother and their families were enjoying excellent cordial relations with the Seleucid monarch Antiochus III the Great.
