Domna Samiou (Greek: Δόμνα Σαμίου; 12 October 1928 – 10 March 2012) was a prominent Greek researcher and performer of Greek 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 (earlier called demotika, nowadays referred to as "paradosiaka" or "traditional"), around the world, appealing not only to the Greek diaspora, but also introducing non-Greek audiences to traditional Greek folk music.
