Montreux Casino (Casino Barrière de Montreux) is a casino located in Montreux, Switzerland, on the shoreline of Lake Geneva.

It has served as the venue for the Montreux Jazz Festival and was rebuilt following a 1971 fire memorialized in the Deep Purple song "Smoke on the Water". Montreux Casino was built in 1881 and had modifications made to it in 1903.

Throughout the twentieth century, the site played host to many great symphony orchestras and well-known conductors.

By the late 1960s, jazz, blues and rock artists began to perform there.

In 1967 the Casino became the venue for the Montreux Jazz Festival, which was the brainchild of music promoter Claude Nobs.

The festival was held there annually and lasted for three days.

The highlights of this era were Keith Jarrett, Jack De Johnette, Bill Evans, Nina Simone, Jan Garbarek, and Ella Fitzgerald.
