Days of Thunder is a 1990 NASCAR racing simulation video game loosely based on the 1990 movie Days of Thunder. The game utilized elements from the movie, using a movie license from Paramount Pictures, for its graphical elements, plot and music soundtrack.

It was released for the PC, the NES, the Game Boy and many other formats. It was created by Argonaut Software and distributed by Mindscape Group. In 2009 Freeverse released an updated version for the iOS.

In the PC version, gameplay consisted of setting up the car, qualifying, and then the actual race event. If the player finished in a high enough position they would progress to the next circuit. Damage was calculated not by realistic damage displayed on the car but a "cracked dashboard" bar indicator, with cracks appearing along the dashboard when the player hits something.

The in-game graphics in the PC version paled in comparison to the still-screen graphics it had. This was due to polygonal graphics being used as opposed to sprites, rendering the car, track, and trackside details in untextured 3D polygons.
