Insector X (インセクターX, Insekuta X) is a horizontally scrolling shooter developed by Hot-B and released in arcades by Taito in 1989. It was ported to the Mega Drive and Famicom.

The player controls an insect-sized warrior named "Kai", who takes on a vast army of cyborg insects to free the insect world from the dark ruler queen. The game uses two buttons: one for an upgradable main shot, and another for a seemingly random selection of secondary weapons.
