Alexandros Markeas (born 18 November 1965) is a Franco-Greek composer of instrumental contemporary music.
After a year of law studies in Athens he entered the Conservatoire de Paris (CNSMD) in the class of Gabriel Tacchino and then in that of Alain Planès.
In addition, he was selected to follow the composition and computer music curriculum of the IRCAM.
To this compositional approach, Alexandros Markeas adds a theatrical dimension, allowing him to escape from "pure music".
At some time he was a professor of generative improvisation at the Conservatoire de Paris (CNSMD).
