In Greek mythology, the name Polypheides or Polyphides (Πολυφείδης) may refer to:
Son of Mantius and brother of Cleitus. He was granted prophetic skills by Apollo and became the best seer among mortals after the death of Amphiaraus; he dwelt in Hyperesia and had a son Theoclymenus. A slightly different account of his life was given by Pherecydes: according to it, Polypheides married Aechme, daughter of Haemon, and settled in Eleusis, where two sons, Theoclymenus and Harmonides, were born to him.
Lord of Sicyon, to whom Agamemnon and Menelaus were entrusted by their nurse after the murder of Atreus. He further sent them to Oeneus.
