Ibycus of Rhegium was a Greek lyric poet active in the sixth century BCE. He was a native of Rhegium in southern Italy but left his homeland, possibly due to political unrest, and spent much of his career at the court of Polycrates, the tyrant of Samos. Ancient tradition records that he was murdered at Corinth, though the details are uncertain.

His poetry survives only in fragments. He composed large-scale choral narratives on mythological themes, similar in style to his predecessor Stesichorus. He also wrote personal monodic lyrics, primarily love poetry celebrating youthful beauty, which were noted for their vivid imagery and emotional voice.

Ibycus is a significant figure who bridged the traditions of choral narrative and personal lyric. His love poetry was highly regarded and influenced later poets, securing his place among the Alexandrian canon of nine lyric poets. His lasting cultural memory is attested by the proverbial story of his murder and the cranes that were said to have revealed his killers.
