La Bottine Souriante (LBS) is a folk band from Canada. The band specializes in traditional Québécois music, often with a modern twist.

Formed in 1976 by Yves Lambert, Andre Marchand, and Mario Forest, they have toured extensively through Europe and North America. In 1990, the band integrated a four-piece horn section with traditional instruments, such as the accordion, fiddle, guitar, piano and double bass, in order to add an element of jazz to their music. In 1998, they contributed a song to the Canadian Celtic music compilation album by The Chieftains, Fire in the Kitchen.

The group's name means "the smiling boot", which refers to the appearance of a work boot with worn-out soles.
