Georges Aperghis (born 23 December 1945 in Athens, Greece) is a Greek composer working primarily in the field of experimental music theater but has also composed a large amount of non-programmatic chamber music. He is married to actress Édith Scob and lives in France.
His works are often very flamboyant and exhibitionist, sharing a kinship with the work of Vinko Globokar, though Aperghis' music is far less violent and much more playful. He studied with Iannis Xenakis and founded the music and theater company ATEM (Atelier Théâtre et Musique). He was a "composer in residence" in Strasbourg, France.
