André Renard (25 May 191120 July 1962) was a Belgian trade union leader and political theorist who, in the aftermath of World War II, became an influential figure within the Walloon Movement. Born into a working class family, Renard was as a metalworker in the Liège region in Wallonia in the era of the Great Depression before becoming involved in the Federation of Metalworkers of Liège ("Fédération des métallurgistes de Liège") in 1937. He established an underground trade union in German-occupied Belgium during the Second World War which sought to unite socialist and communist unions within a united trade union ("syndicat unique"). He emerged as a powerful figure within trade unionism in the aftermath of the Liberation of Belgium.
