Giannis Chasavetis (Greek: Γιάννης Χασαβέτης; Smyrna, 1899 – Athens, 1943) was a Greek bouzouki virtuoso. At the age of 23, Chasavetis left his homeland as a refugee from the 1922 destruction of Smyrna. Settling in Athens, he met and worked with other prominent rebetiko artists of his time. The main theme of the songs that he played is the hardship that Greek refugees faced at that period.
