Stargunner is a horizontal scrolling shooter computer game developed by Apogee Software. It was released on November 19, 1996, and it has the distinction of being the last title sold under the Apogee brand name.

Stargunner was one of the first shoot-em-up games to use pre-rendered 3D graphics, which made it one of the most beautiful and detailed scrolling shooters of its time. Pre-rendered 3D graphics were also used in Donkey Kong Country and Killer Instinct. Each of its three registered episodes followed a specific setting with complementary enemies (space, land, and underwater), the introductory (shareware) episode providing a sampling from all three themes.
