Denizen is an action computer game published by Players Software in 1988 for the ZX Spectrum.

The enemies attack the player merely by contact, draining the character's health in a manner similar to Gauntlet.

Items that can be collected include single-use keycards to open locked doors, ammunition, and a torch which allows better vision in dark areas.

Denizen received poor reviews, with criticism being levelled at the slow character movement.
