Vallée-Jonction is a municipality in the Municipalité régionale de comté de la Nouvelle-Beauce in Quebec, Canada. It is part of the Chaudière-Appalaches region and the population is 1,864 as of 2021.

In 1881, the Lévis and Kennebec Railway opened a train station between Sainte-Marie and Saint-Joseph-de-Beauce named Beauce-Jonction. When the Quebec Central Railway bought it in 1882, Beauce-Jonction became one of the most important train stations on the Lévis-Sherbrooke line.

In 1900, the parish of L'Enfant-Jésus was constituted, and part of its territory was detached in 1924 to form a village of the same name, but known locally as Beauce-Junction, after the post office opened in 1883. The village changed its name to Vallée-Jonction in 1949. L'Enfant-Jésus and Vallée-Jonction amalgamated in 1989 to form the current municipality.
