Antinous (Ancient Greek: Ἀντίνοος), son of Eupeithes, is the boldest and most violent of Penelope's suitors in Homer's Odyssey. He leads the wooers in devouring Odysseus' house, plots Telemachus' death at sea, assaults the disguised king with a stool, and is the first suitor slain when Odysseus strings the bow.

I.Among the suitors
With Eurymachus and Amphinomus, Antinous stands among the three most prominent wooers. Homer presents him as mean-spirited and over-confident: he answers Telemachus with scorn in the assembly, blames Penelope's shroud stratagem for the suitors' long stay, and shows no regard for xenia while the company consumes Odysseus' livestock.
When Telemachus voyages to Pylos and Sparta, Antinous mans an ambush in the strait between Ithaca and Same, by the rocky isle Asteris. Athena helps the prince avoid the trap.
II.Death and later tradition
After Odysseus returns in beggar's rags, Antinous strikes him with a chair — an outrage even some of the other suitors disapprove. In the Great Hall he is the first to die: Odysseus shoots him through the throat as he lifts a cup of wine. Eurymachus then tries to shift all blame onto the fallen chief.
A later account preserved by Apollodorus holds that Penelope was seduced by Antinous and sent away by Odysseus to her father Icarius — a strand opposed to Homer's faithful queen.
