Lamprocles the Athenian (Λαμπροκλῆς ὁ Ἀθηναῖος) was a 5th-century BCE Athenian poet and musician. Ancient sources identify him as a son of the musical theorist Damon and a student of Socrates, placing him within key intellectual circles of Classical Athens [1]. His primary significance lies in musical innovation: the Suda credits him with being the first to transpose the Mixolydian mode from tragedy to the dithyramb, a choral hymn to Dionysus [1][2].

Only one work is attributed to him, a hymn to Athena (Ὕμνος εἰς Ἀθηνᾶν). This hymn is lost, surviving solely as a title recorded in the Suda, with no textual fragments extant [1][2].

Lamprocles represents a documented point in the evolution of Greek musical practice. His reported innovation illustrates the experimentation with musical harmoniai across genres, and his associations with Damon and Socrates situate him at an intersection of musical and philosophical thought in late 5th-century Athens [1][2].
