The 1957 World Sportscar Championship season was the fifth season of the FIA World Sportscar Championship. It was a series for sportscars that ran in many worldwide endurance events. It ran from 20 January 1957 to 3 November 1957, and comprised seven races.

The World Sportscar Championship was the world series run for sports car racing by the FIA from 1953 to 1992. The championship evolved from a small collection of the most important sportscar, endurance, and road racing events in Europe and North America with dozens of gentleman drivers at the grid to a professional racing series where the world's largest automakers spent millions of dollars per year.
