Guy Béart (born 16 July 1930) is a French singer and songwriter.
He was born Guy Béhart-Hasson in Cairo, Egypt, to a family of Spanish, Swiss, and Russian background. His religious background is unclear, having been referred to as both Jewish and Christian. His father's work as an accountant and business consultant saw the family move frequently, leading to a childhood spent in France, Greece, and Mexico, in addition to Egypt. Between the ages of 10 and 17 his family settled in Lebanon where his interest in music developed to the point that he left for Paris to study at the "École nationale de musique". In addition to music, he also obtained a degree in engineering.
