Cabal (カベール Kabēru?) is a 1988 arcade video game originally developed by TAD Corporation and published in Japan by Taito Corporation and in North America and Europe by Fabtek. In this game, the player controls a commando, viewed from behind, trying to destroy various enemy military bases. The game was innovative for the era, and a modest success in sales.

Cabal was ported to several home computers of the era, including the DOS computers, Amstrad CPC, Commodore 64, ZX Spectrum, Atari ST and Amiga. It was also ported to the Nintendo Entertainment System console by Rare. The quality of these ports varied based on the target system's capabilities.

Cabal was followed in 1990 by Blood Bros., though the sequel had a western theme as opposed to Cabal's Vietnam-era theme.
