In Greek mythology, Acamas or Akamas (Ancient Greek Ἀκάμας) is the Athenian prince, son of Theseus and Phaedra and brother of Demophon, who fights at Troy, is named among the men in the Wooden Horse, and helps free his grandmother Aethra at the sack. Distinct from Antenor's Trojan son, the Thracian captain of the same name, and Penelope's Dulichian suitor.

I.Exile and Troy
Phaedra bore Acamas and Demophon to Theseus. After Menestheus took the Athenian throne, the brothers grew up in exile on Euboea under Elephenor. Later sources send Acamas (with Diomedes) to negotiate Helen's return before the war; during a stay at Troy he is said to have fathered Munitus by Priam's daughter Laodice, the boy raised by Aethra.
Hyginus and Virgil count him among the warriors in the Wooden Horse. Apollodorus has Demophon and Acamas lead Aethra away from Helen's house at the fall of Troy. Pausanias lists him among the eponymous Athenian tribal heroes and shows him in Polygnotus' Delphic painting of the sack.
II.Homonyms
Homer's Iliad does not name Theseus' son among the Achaean leaders; later epic and tragedy supply the Athenian Acamas. The atlas keeps him strictly separate from acamas-antenorid (Trojan), acamas-thracian, and the Dulichian suitor — same name, different houses.
