Lac Le Jeune is a lake and provincial park in British Columbia, Canada, located approximately 37 kilometres south of Kamloops or 47 kilometres north of Merritt.
The lake is located within a 213-hectare provincial park run by the British Columbia Ministry of the Environment, and is a popular fishing spot for "fighting" Rainbow Trout. It is a summer holiday spot with 144 campgrounds and the Lac Le Jeune resort.
The lake has had several names including "Batchelor", "Chuhwels", and "Le Jeune Lake". The current name was adopted in 1956, and commemorates Father Jean-Marie-Raphaël Le Jeune, a French Catholic priest who spent much of his life in the region.
