Section Z is a side-view shoot-em-up by Capcom originally released as a coin-operated video game in 1985. A home version was released for the Nintendo Entertainment System in 1987.

Set in an unspecified year during the third millennium, the player takes the role of an astronaut sent to infiltrate and destroy a space station orbiting near the Earth that is actually the secret base of an alien empire known as the Balangool.

The NES version features three stages, each comprising 20 sections (for a total of 60 sections), which are full-fledged levels in this version, although not all sections need to be visited to complete the game. In contrast to the alphabetical sections in the arcade version, the sections in the NES version are numbered instead. The first stage begins at Section 00, which is the outer perimeter of the space station and then proceeds to enter Section 01, the first actual corridor of the base. At the end of most sections, the player will choose to enter one of two transporters, each taking player to a different section of the base. Some transporters will take the player to a previous section while others cannot be opened until the player has fulfilled a certain condition and will kill the player if they try to enter. The objective of each stage is to destroy the two power generators located at different sections of each stage in order to open the path to the final section of each stage (Sections 19, 39, and 59 in that order) and face the boss.
