Didier Hassoux is a French investigative journalist and political writer. He is the co-author of six books about French politics, and he writes for the satirical newspaper Le Canard enchaîné.
During the 2017 French presidential election, center-right candidate François Fillon said Hassoux's sixth book, Bienvenue Place Beauvau, suggested President François Hollande ran a shadow cabinet to spread rumours about his opponents. Hassoux denied this was the case.
