In Greek mythology, Terpsichore (/tərpˈsɪkəriː/; Ancient Greek: Τερψιχόρη, "delight in dancing") is one of the nine Muses and goddess of dance and chorus. She lends her name to the word "terpsichorean", which means "of or relating to dance".

Terpsichore is usually depicted sitting down, holding a lyre, accompanying the dancers' choirs with her music. Her name comes from the Greek words τέρπω ("delight") and χoρός ("dance").

According to Hesiod's Theogony, Zeus lay with the Titan Mnemosyne each night for nine nights in Piera, producing the nine Muses.

According to Apollonius of Rhodes, Terpsichore was the mother of the Sirens by the river god Achelous. The Etymologicum Magnum mentions her as the mother of the Thracian king Biston by Ares. According to the Byzantine scholar Eustathius, Terpsichore was the mother of the Thracian king Rhesus by the river god Strymon.
