Klytios is the Greek form of a name borne by several minor characters in Greek mythology. It is derived from Greek κλυτός (klytos), meaning "famous, noble." Variants include Clytius and Clytia.
In mythology, Klytios (often spelled Clytius) appears as the name of a Giant, a warrior, an Argonaut, and other figures. One of the most prominent is the Giant Clytius, a son of Gaia, who was killed by Hecate during the Gigantomachy. Another Clytius was an Argonaut and a son of King Eurytus of Oechalia, brother to Iole and Iphitus; he, along with his brother Iphitus, accompanied the Argonauts on their quest for the Golden Fleece. Some accounts list him among the Lapiths, participating in the battle with the Centaurs at the wedding of Pirithous and Hippodamia, where he slew the centaur Clanis.
The name appears in other contexts: a Cypriot Clytius raised the famous archer Teucer? However, concrete connections remain obscure in the available fragments. Currently
