Corinna was a lyric poet from Tanagra in Boeotia, traditionally considered active during the 5th century BCE. Ancient sources portray her as a contemporary and rival of the poet Pindar, even claiming she defeated him in poetic competitions, though the historicity of these accounts is uncertain. Some modern scholars, based on linguistic analysis of her surviving work, propose a later date in the 3rd century BCE, suggesting her association with Pindar may be a later literary invention. This dating remains a subject of ongoing debate.

Her work survives only in fragments, chiefly preserved on papyri. She was known for a collection often titled Asmata or Meliae. These narrative fragments focus on local Boeotian myths, such as the contest between the mountains Cithaeron and Helicon. She composed in a literary form of the Boeotian dialect, which is related to Aeolic Greek.

Corinna is significant as one of the few named female poets from ancient Greece. Her poetry offers valuable insight into regional Boeotian traditions, providing a contrast to the more dominant Panhellenic myths. Her enduring reputation, whether historically precise or not, underscores the recognition of women's literary achievements in antiquity. The scholarly controversy over her true date illustrates the challenges inherent in interpreting fragmentary texts.
