In Greek mythology, Melampus (; Ancient Greek: Μελάμπους, romanized: Melámpous) was a legendary soothsayer and healer, originally of Pylos, who ruled at Argos. He was the introducer of the worship of Dionysus, according to Herodotus, who asserted that his powers as a seer were derived from the Egyptians and that he could understand the language of animals. A number of pseudepigraphal works of divination were circulated in Classical and Hellenistic times under the name Melampus. According to Herodotus and Pausanias (vi.17.6), on the authority of Hesiod, his father was Amythaon, whose name implies the "ineffable" or "unspeakably great"; thus Melampus and his heirs were Amythaides of the "House of Amythaon". Maurice de Guérin made him one of the characters of the first Western prose poem, "The Centaur", in 1835.
