The 2003 FIA Sportscar Championship was the third season of FIA Sportscar Championship, an auto racing series regulated by the Fédération Internationale de l'Automobile and organized by the International Racing Series Ltd. It was the seventh and final season of the series dating back to the International Sports Racing Series of 1997. The series featured sports prototypes divided into two categories, SR1 and SR2, and awarded championships for drivers, constructors, and teams in both classes. The series began on 13 April 2003 and ended on 21 September 2003 after seven races in Europe.
Jan Lammers of the Netherlands won his second consecutive drivers championship for his Racing for Holland Dome outfit, sharing the championship with countryman John Bosch. Mirko Savolid and Pierguiseppe Peroni also earned a repeat drivers championship in the SR2 category for Lucchini Engineering after winning in five of seven events.
The 2003 calendar for the championship featured seven events, six in the traditional 2-hour 30-minute format plus the addition of the 1000 km Spa run in conjunction with the British GT Championship, a return to the 1000 km format last utilized in 1988. Circuito do Estoril began the season in the first visit to Portugal for the series, while Autodromo Nazionale Monza and Donington Park both returned to the series with events held in conjunction with the International Formula 3000 series; Donington would also serve as the first race in the championship to be held at night. The EuroSpeedway Lausitz would share its event with the Champ Car World Series, while Circuit Paul Armagnac and Motopark Oschersleben were also new events to the series.
