The 1997 International Sports Racing Series season was the first season of International Sports Racing Series (later known as the FIA Sportscar Championship). It was a series for sportscar style prototypes broken into two classes based on power and weight, called SR1 and SR2. It began on July 6, 1997, and ended November 9, 1997, after 4 races.

As a new series, and with only 4 races, no championships were awarded for teams or drivers.
