Action civique de Saint-Léonard was a municipal political party that existed from 1984 to 1986 in the suburban community of Saint-Leonard in Montreal, Quebec, Canada. The party claimed more than five hundred members in March 1986 and held one seat on the Saint-Leonard city council. After the 1985 by-election, Moschella called for a united opposition party to challenge Renaud's administration in the next general election. He helped form the new Unité de Saint-Léonard party in October 1986 and wound down Action civique shortly thereafter.
