Corinna was a lyric poet from Tanagra in Boeotia, active during the 5th century BCE. Ancient sources describe her as a contemporary and rival of the famous poet Pindar. According to these sources, she even defeated him in poetic competitions, though the historical accuracy of these stories is uncertain. Some modern scholars, based on analysis of the language in her surviving poetry, argue she may have lived later, in the 3rd century BCE, suggesting her connection to Pindar could be a later invention. This dating remains a point of scholarly debate.

Her work survives only in fragments, primarily preserved on papyri. She was known for a collection often titled Asmata ("Songs") or Meliae ("Nymphs"). The fragments are narrative poems that focus on local Boeotian myths, like the contest between the mountains Cithaeron and Helicon. She wrote 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 provides valuable insight into regional Boeotian traditions, contrasting with the more widely known Panhellenic myths. Her lasting reputation, whether historically precise or not, highlights the recognition of women's literary achievements in antiquity. The debate over her true date illustrates the challenges scholars face when working with fragmentary texts.
