This is a list of cancelled Nintendo 64 video games.
The console was a moderate success with its 32.93 millions units sold; it was three times as much as one competitor, the Sega Saturn, but only a third of the sales of its other competitor, the original PlayStation.
Third party game developers cancelled multiple games for the system, with commonly-cited reasons including its lower sales numbers compared to the PlayStation, its unconventional controller, and Nintendo's decision to stick with the game cartridge format, which was more costly to produce and featured far less storage than the PlayStation's CD-ROMs.
Additionally, the brief lifespan and commercial failure of the 64DD, a Japan-only Nintendo 64 add-on, led to many of its games being cancelled or reworked for release on the standard Nintendo 64.
This list documents all known games that were announced for the Nintendo 64 at some point, but did not end up being released for it in any capacity.
