Vassilis Tsitsanis (1915-1984) was a Greek singer, songwriter, and bouzouki player, considered one of the most influential figures in Greek music. He is often referred to as the "architect" of modern Greek popular music.

Tsitsanis was born on January 18, 1915, in Trikala, Greece. He began playing the bouzouki at a young age and eventually moved to Athens in the late 1930s to pursue a career in music. His innovative style and compositions played a significant role in the evolution of rebetiko, a genre of Greek music associated with urban working-class culture.
