Saint-Léonard-d'Aston ({{IPA|fr|sɛ̃ leɔnaʁ dastɔn}}) is a municipality in Nicolet-Yamaska RCM in the province of Quebec, Canada. The population as of the Canada 2021 Census was 2,530. The municipality is situated along Route 155, partway between Drummondville and Trois-Rivières. Autoroute 20 and a major intercity railway line, part of Canadian National Railway over which VIA Rail Canada passenger trains also operate, cross through the town. Until the completion of the northern branch of Autoroute 55 in October 2006, Saint-Léonard-d'Aston was a common waypoint for those who travelled between Trois-Rivières and Sherbrooke.
