Sega Technical Institute (STI) was an American video game developer owned by Sega. Founded by the Atari veteran Mark Cerny in 1990, STI sought to combine elite Japanese developers, including the Sonic Team programmer Yuji Naka and his team, with new American talent. STI developed games for Sega Genesis, including several Sonic the Hedgehog games, before it was closed at the end of 1996.

The Sonic & Knuckles cartridge features a "lock-on" adapter that allows it to be physically attached to other Genesis cartridges.
Retrospectively, STI's games have been considered important to the Sega Genesis.
