This is a list of video games developed and/or published by Koei Tecmo. Some games were only published by Koei Tecmo in a specific region or for a specific platform; these games will only list the publisher relevant to this list and will be notated appropriately. Also, many games have different release dates for different regions, platforms, or re-releases. For the purposes of simplicity, and to ensure easy automated sorting, only the earliest date will listed on this table.
