Gaston Barreau (7 December 1883 – 11 June 1958) was a French football player and coach.

[1] He played primarily for FEC Levallois, but was also honored with 12 selections in the France national team between 1911 and 1914.

Unable to free himself from his obligations at the Academy of Music in July 1930, he could not accompany France in the debut edition of the World Cup.

When Barreau was appointed sole coach on 24 February 1936, it was the end of the era of the managing committee.

He was still serving with the staff of the "Bleus" at the time of his death in 1958, the day of the Yugoslavia-France match at the Swedish World Cup.
