Márkos Vamvakáris (Greek: Μάρκος Βαμβακάρης; 10 May 1905 – 8 February 1972), was a rebetiko musician. He is universally referred to by rebetiko writers and fans simply by his first name, Márkos. The great significance of Vamvakaris for the rebetiko is also reflected by his nickname: the "patriarch of the rebetiko".
