In Greek mythology, Amphinomus, also Amphínomos (Ἀμφίνομος; literally "grazing all about"), was the son of King Nisos and one of the suitors of Penelope that was killed by Telemachus. Amphinomus was considered the best-behaved of the suitors. Despite Odysseus's warning, he was compelled by Athena to stay, as he had been a suitor nonetheless. He was killed by a spear thrown by Telemachus during the murder of the suitors; ironically, Amphinomous had twice tried to dissuade the suitors from killing Telemachus. Amphinomus had been Penelope's favorite suitor and he was the most likely to marry her.
