Nossis (Greek: Νοσσίς) was a Hellenistic poet from Locri in southern Italy. She primarily wrote epigrams for religious dedications and epitaphs.Her epigrams were inspired by Sappho, whom she claims to rival. She may have also been influenced by Erinna and Anyte. Nossis states in her work that her mother was named Theuphila, the daughter of Cleouchas. In another epigram, she mentions that she had a daughter named Melinna, who is possibly the poet Melinno.
