In Greek mythology, Iphiclus (Ancient Greek Ἴφικλος) of Phylace is son of King Phylacus and Clymene, father of the Trojan War leaders Protesilaus and Podarces, and famed for his speed. Melampus cures his infertility and receives his cattle as reward; he is also counted among the Argonauts. Distinct from Iphicles (Heracles' twin), Iphiclus son of Thestius, and the Cretan prince Iphiclus.

I.Son of Phylacus
Iphiclus belongs to the Phylacean house that holds Phylace and Hellas in Homer's Catalogue. By Diomedeia (or a wife of that name-group) he fathers Protesilaus — first Greek to die at Troy — and Podarces, who takes command of the Phthian ships after his brother's death.
Hesiod and the Argonautic poets praise his fleetness of foot. Melampus, bargaining for Neleus' cattle-quest, cures Iphiclus of childlessness and wins the famous herd as fee — the Melampodid bridge into this house.
II.Argonaut and Homonym care
Apollonius and Valerius Flaccus list Iphiclus among those who sail for the Fleece. Homer's Iliad remembers him chiefly as the father whose sons lead from Phylace.
The atlas id iphiclus-phthian is this Phylacean prince alone — not Iphicles son of Alcmene, not the Calydonian Iphiclus son of Thestius, and not Idomeneus' Cretan son.
