List of Atari 7800 games
This is a list of games for the Atari 7800 ProSystem, or simply the Atari 7800 video game console, totaling to games. It was a video game console released by Atari Corporation in January 1986. A test market release had occurred two years earlier under Atari Inc. The 7800 was designed to replace Atari Inc.'s unsuccessful Atari 5200 and later to re-establish Atari Corp.'s market supremacy against Nintendo and Sega. With this system, Atari Inc. addressed all the shortcomings of the Atari 5200: it had simple digital joysticks; it was almost fully backward-compatible with the Atari 2600; and it was affordable.
In addition to the aforementioned games, there also exists aftermarket homebrew games.

Unreleased games
- Klax. The game was nearly completed when canceled. For years, it was traded privately until a ROM was made available to the general public. Later, the developer appeared to create additional levels for the community.
- Gato. Released on the XE Game System, an Atari 7800 version was started but not completed beyond a simple demo.
- Missing in Action. A side scrolling adventure that was about 85% complete when cancelled. The game is mostly playable with some later collision detection issues requiring cheats to get past.
- Pit-Fighter. An early demo of the game has been found, with crude graphics, no sound and poor collision detection.
- Plutos
- Rescue on Fractalus!. A conversion of the popular computer game was released by GCC in 2004. The game was partially complete with a running engine but no enemies.
- Sirius
- Toki
- Other 7800 games remain lost, despite indications that development occurred. The most notable of these are Skyfox and ElectroCop.
