Gustave Doret (20 September 1866 – 19 April 1943) was a Swiss composer and conductor.

He studied at the Berlin Academy of Music with Joseph Joachim, and then at the Conservatoire de Paris with Théodore Dubois and Jules Massenet.

His career as a conductor began in 1894 in Paris, where he led the first performance of Debussy's Prélude à l'après-midi d'un faune.

His only instrumental works were two orchestral pieces, a string quartet, and a piano quintet.

His work was part of the music event in the art competition at the 1912 Summer Olympics.
