Metal Gear Acid (also spelled Ac!d; commonly abbreviated as MGA) is a video game developed by Konami Computer Entertainment Japan for the PlayStation Portable handheld game console. It is part of the Metal Gear series, and was first unveiled at E³ 2004 in May. It was released in Japan on December 16, 2004, and in North America on March 22, 2005.

While the Metal Gear series, despite being stealth-based, has always had a heavy influence of action, Metal Gear Acid is not action-oriented, but focuses on turn-based strategy (this is possibly why the game's logo lacks the "Tactical Espionage Action" tagline featured on all of the Metal Gear Solid games). It uses a trading card-based system to control the main character's movements and actions. This system is similar to the one used in the Yu-Gi-Oh! games, which are also produced by Konami.

Metal Gear Acid is a "side-story" and not part of the series' main storyline (similar to the earlier Metal Gear: Ghost Babel). While the game features an all-new cast, characters and items from the previous Metal Gear games (as well as other games by Hideo Kojima, such as Policenauts, Boktai and Zone of the Enders) are depicted on the cards used by the player.
