# List of cancelled Master System games

This is a list of cancelled Master System video games. The Master System is a video game console released by Sega in 1986, a western remodel of their Japanese "Mark III" console. While successful in Europe and Brazil, the system never gained a foothold in Japan or North America and was largely superseded in the early 1990s by its successor, the Sega Genesis, leading to several games being cancelled. Due to their similar hardware capabilities and architecture, many of these games had ports that were developed concurrently for Sega's Game Gear handheld system, though several of these were also cancelled. This list documents all known games that were confirmed to be announced or in development for the Master System at some point, but did not end up being released for it in any capacity.
