Corinna or Korinna (Ancient Greek: Κόριννα, romanized: Korinna) was an ancient Greek lyric poet from Tanagra in Boeotia. Although ancient sources portray her as a contemporary of Pindar (born c. 518 BC), not all modern scholars accept the accuracy of this tradition. When she lived has been the subject of much debate since the early twentieth century, proposed dates ranging from the beginning of the fifth century to the late third century BC.

Corinna's works survive only in fragments: three substantial sections of poems are preserved on second-century AD papyri from Egypt; several shorter pieces survive in quotations by ancient grammarians. They focus on local Boeotian legends, and are distinctive for their mythological innovations. Corinna's poetry often reworks well-known myths to include details not known from any other sources. Though respected in her hometown, Tanagra, and popular in ancient Rome, modern critics have often regarded her as parochial and dull; her poetry is nonetheless of interest as she is one of the few female poets from ancient Greece whose work survives.
