The 2003 Proximus 24 Spa was the 56th running of the Spa 24 Hours and the sixth round the 2003 FIA GT Championship. This event combined the FIA GT's two classes (GT and N-GT) with cars from national series and one-make series, designated G2 and G3. It took place at the Circuit de Spa-Francorchamps, Belgium, on 25 and 26 July 2003.

This race marked the only time in the history of the FIA GT Championship that the slower of the two classes (N-GT in this case) managed to win a race overall.
