This is a list of video games developed and/or published by Tecmo, prior to its merger with Koei, released by Tecmo Koei under the Tecmo label or under its former name Tehkan. Some games were only published by 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 is listed on this table.
