Das Boot: German U-boat Simulation is a submarine simulator game designed by Paul Butler & Rick Banks and published in 1990 for Amiga and MS-DOS systems by Three-Sixty Pacific.

The player takes command of a German Type VII U-boat and plays missions against the Allies which involve combat against aircraft, anti-submarine warships, and other submarines.

The game was touted to feature 256 VGA Color, 3D Views, and historical realism.

The MS-DOS version was released on 3.5" floppy disks and came packaged with a copy of the novel of the same name.

Computer Gaming World in 1991 panned the game as a serious submarine simulator, noting several issues such a frustrating user interface, unrealistic mechanics, and limited information presented to the player compared to other games of the same genre.
