The primary son of Odysseus in Greek mythology is Telemachus , born from his marriage to Penelope.

Main answer

  • In Homer’s Odyssey , Odysseus is described as the father of Telemachus with his wife Penelope, and this is the best‑known and most widely accepted tradition.
  • Later myths also give Odysseus additional sons by other women, such as Telegonus with the sorceress Circe, but these are secondary traditions compared with Telemachus’s role in the epic.

So, if someone asks “who was the son of Odysseus,” the standard answer is Telemachus.
