Guillaume de Fontenay (born March 6, 1969) is a Canadian film director and screenwriter from Montreal, Quebec. He is best known for his feature debut Sympathy for the Devil (Sympathie pour le diable), which received three nominations at the 8th Canadian Screen Awards in 2020.

Before Sympathy for the Devil, de Fontenay worked primarily in theater and advertising, and in 2012 he made the short film Le Retour Triptyque. He first took on directing Sympathy for the Devil in the mid-2000s after reading the book by war correspondent Paul Marchand, but the film was delayed due to various production difficulties, including Marchand's death in 2009, and was not completed or released until 2019.

At the Canadian Screen Awards, de Fontenay was nominated alongside Guillaume Vigneault and Jean Barbe for Best Adapted Screenplay, and the film was also nominated for the John Dunning Best First Feature Award. Vigneault, Barbe, and de Fontenay also received a Prix Iris nomination for Best Screenplay at the 22nd Quebec Cinema Awards, where de Fontenay was also nominated for Best Director.
