Apogee software is a software developer and publisher from the early 90s who had a close relationship with id Software during the development of Commander Keen and Wolfenstein 3D. However, Apogee software never had any direct involvement with the development of Doom, though it is an integral part of id Software's heritage.

The Apogee software label disappeared in favor of 3D Realms when Terminal Velocity and Duke Nukem 3D came along.
