The mountains classification is a secondary competition in the Tour de France, that started in 1933. It is given to the rider that gains the most points for reaching mountain summits first. The leader of the classification is named the King of the Mountains, and since 1975 wears the polka dot jersey, a white jersey with red polka dots.

The Tour de France is an annual men's multiple-stage bicycle race held primarily in France. It is the oldest of the three Grand Tours and is generally considered the most prestigious.
