Lasus of Hermione was a Greek lyric poet of the 6th century BC from the city of Hermione in the Argolid. He is known to have been active at Athens under the reign of the Peisistratids. Pseudo-Plutarch's De Musica credits him with innovations in the dithyramb hymn. According to Herodotus, Lasus also exposed Onomacritus's forgeries of the oracles of Musaeus.
