The President of France during the Vietnam War was Charles de Gaulle. He served as the President of France from 1959 to 1969. De Gaulle's presidency coincided with a significant period of the Vietnam War, which lasted from the mid-1950s to the mid-1970s. France's involvement in Vietnam began before de Gaulle's presidency, with the First Indochina War, but he played a role in shaping France's policies and decisions regarding its withdrawal from Vietnam and the subsequent negotiations that led to the Geneva Accords in 1954.
