A stereoscopic video game (also S-3D video game) is a video game which uses stereoscopic technologies to create depth perception for the player by any form of stereo display. Such games should not be confused with video games that use 3D game graphics on a mono screen, which give the illusion of depth only by monocular cues but lack binocular depth information.

Stereoscopic video games have been available for several years for PCs through the Nvidia 3D Vision and other platforms including AMD HD3D, DDD TriDef that use compatible hardware and active shutter 3D glasses. For video game consoles, however, stereoscopic 3D support must be specifically built into each game. Potential stereoscopic game support is available, for instance, on Xbox 360, PlayStation 3, Xbox One, Wii U and PlayStation 4. Nintendo 3DS is fully designed for autostereoscopic games.

Although no longer considered a key feature for successful game development by as many as during the stereoscopic 3D hype in 2010, stereoscopic support for video games is still considered a minor enhancement to video games. Many individuals consider it to be the most significant enhancement to video games. One of the reasons for the technology's lack of success was that the surprise effect quickly wears off.

A study at the University of Derby showed that converted 2D games do not transfer very well to stereoscopic 3D and concluded: "... games targeted to stereoscopic 3D audiences and devices must be designed from the start with stereoscopic 3D in mind." Therefore, stereo video games must have elements that can only be achieved in S-3D for a proper stereoscopic immersion.

For example, in the game Super Stardust HD, asteroids stand out from the plane. It makes navigation easier and serves a fundamental purpose. Super Mario 3D Land is another example for easier navigation and furthermore the game plays with depth, e.g. with Escher-style perspective puzzles.

Developers also need to mind perceptual problems such as stereo window violations and occlusion of virtual objects. Another scientific paper showed that S3D vision can measurably change player behavior depending on actual game design.

Recent developments of consumer virtual reality headsets such as for example Oculus Rift, HTC Vive, PlayStation VR, Fove, and Open Source Virtual Reality also include stereoscopic support as one of their features. The entire development trend of games and other software for such head-mounted displays remains to be seen.

There are two primary rendering techniques employed in stereoscopic video games: 2D + depth rendering, and dual rendered 3D.
