Technosoft (also known as Tecno Soft) was a Japanese video game developer that is best known for the Thunder Force series of shooters for the Mega Drive/Genesis. Their initial title was developed for the Japanese Sharp X1, with later ones for the Mega Drive/Genesis, Sony PlayStation, and Sega Saturn.

Other notable Tecno Soft games for the Sega Mega Drive/Genesis include Herzog Zwei, regarded as the world's first real-time strategy game, the conversion of TurboGrafx 16 game Devil's Crush, dubbed "Dragon's Fury" and released in North America by Tengen, and Elemental Master.

In 2001, the company was purchased by pachinko maker Twenty-one Company and was merged into its R&D division.

In 2006, the URL Tecnosoft.com was registered and updated. However, as of January 2008, no updates other than "We will restart soon! Please wait for a while." and "THUNDERFORCE is a registered trademark." have been added to the website. However, with the announcement of Thunder Force VI, the copyright for the game has been apparently turned over to one of the series' creators and may no longer apply.

Some Technosoft staff left to start game developer CAProduction in 1993.
