Lycomedes was a king of Scyros.
Thetis brought her young son Achilles to him and asked him to bring him up as a girl in order to avoid the Trojan War. Lycomedes' name means 'wolf cunning', from lycos, 'wolf and medea, 'cunning', 'craft'. This would seem to apply to the king himself rather than to Thetis' ruse; he would certainly have needed cunning to carry through the disguise.
