Domna Samiou (Greek: Δόμνα Σαμίου; 12 October 1928 – 10 March 2012) was a prominent Greek researcher and performer of Greek folk music and Turkish folk music. She received her first formal musical training from Simon Karas. For over half a century she collected, recorded, and performed traditional songs of Greece (demotika), around the world, appealing not only to the Greek diaspora, but also introducing non-Greek audiences to traditional Greek folk music and Turkish folk music.
