Víctor Hugo Díaz (August 10, 1927 in Santiago del Estero, Argentina - October 23, 1977 in Buenos Aires, Argentina) was a tango, folklore and jazz harmonicist.
Díaz was born to a poor family in the small city of Santiago del Estero. At the age of five he lost his sight when hit by a soccer ball, which led him to play the harmonica. Two years later, after surgery restored his eyesight, he was already performing regularly for a local radio.
