Project I.G.I. (released in North America as Project I.G.I.: I'm Going In) is a tactical first-person shooter video game. It was developed by Innerloop Studios and released in December 2000 by Eidos Interactive. The game received mixed reviews due to shortcomings including a poorly programmed A.I., lack of a mid-game save option, and the lack of multiplayer features. However, it was praised for its sound design and graphics, thanks in part to its use of a proprietary game engine that was previously used in Innerloop's Joint Strike Fighter.

It was followed up in 2003 by I.G.I.-2: Covert Strike.

A prequel titled I.G.I. Origins was announced by publisher Toadman Interactive in 2019 and was being developed by AntiMatter Games with no release date announced. In May 2023, Antimatter Games announced the closure of the development studio.
