(Ἀντίμαχος), a Trojan, who, when Menelaus and Odysseus came to Troy to ask for the surrender of Helen, advised his countrymen to put the ambassadors to death. (Hom. Il. 11.122, &c., 138, &c.) It was Antimachus who principally insisted upon Helen not being restored to the Greeks. (Il. 11.125.) He had three sons, and when two of them, Peisander and Hippolochus, fell into the hands of Menelaus, they were both put to death.

There are three other mythical personages of this name. (Hyg. Fab. 170; Schol. ad Pind. Isthm. 4.104; Ov. Met. 12.460.)
