Grand Star (La Compagnie des Glaces in France) is a 2007 Canadian / French / Belgian co-production science fiction television series loosely based on the novel series La Compagnie des glaces by the French writer Georges-Jean Arnaud. It was filmed in Wallers-Arenberg, France, and originally broadcast in Canada on Space and in France on France 2.

A multiplayer strategy game based on the TV series universe was launched in 2007. In the game, players compete by using their trains to gather money for energy source control.

The series is set in a post-apocalyptic world 100 years after a cataclysmic event plunges the Earth into darkness and an ice age. The world consists of stations connected by a network of railway lines, and the inhabitants are governed by railway companies who tell them that the sun had turned supernova and became extinguished. The show centers on a community of people who lived on a station called Grand Star, as well as other people who still believe in the sun called Renewers, and people of the cold who can survive in the icy world outside. The story revolves around Cal Ragg, who believes he can bring the sun back, and his friends Suki and Kurt Masters.
