NASCAR Racing 2003 Season, or NR2003 for short, is a computer racing simulator. The programming was completed by September 3, 2002 and was waiting for its February 2003 Daytona 500 release date by Papyrus for PC. The game was the last to be released by the company before EA Sports bought the NASCAR license from NASCAR. The game included all of the 2003 NASCAR season tracks and many of the drivers. The game box featured the cars of Jimmie Johnson and Kevin Harvick on the front cover.

The game features a popular multiplayer interface, used by up to 2500 drivers at any one time. This can result in fields of up to 43 human drivers driving simultaneously in online races. There are several online leagues still running, even with the release of countless other stock car sims. Although the Sierra online multiplayer aspect of the game has decreased this game is far from dead or even old. Many private companies have been started to fulfill the need for professional grade multiplayer servers and league management software for this game. In addition, downloading of new mods, updated cars, tracks and templates have allowed users to give the program a fresh look and keep up with real life racing.

NR2003 is also one of the few 'serious' racing simulations which have also been published for the Macintosh, in a Mac OS X version.
