Metal Gear Solid 3: Snake Eater (commonly abbreviated to MGS3) is a stealth-based video game directed by Hideo Kojima. Snake Eater was developed by Konami Computer Entertainment Japan and published by Konami in 2004 for the PlayStation 2. It was well-received publicly and critically, selling 3.6 million copies worldwide and scoring an average of 91% on the review aggregate sites Game Rankings and Metacritic.

The game serves as a prequel to the entire Metal Gear series. It was followed by a direct sequel titled Metal Gear Solid: Portable Ops.

Set in Cold War-era Russia, the story centers on FOX operative Naked Snake as he attempts to rescue a weapons designer and sabotage an experimental superweapon. While previous games were set in a primarily urban environment, Snake Eater adopts a 1960s Soviet jungle setting, with the high tech, near-future trappings of previous Metal Gear Solid games being replaced with the wilderness. While the setting has changed, the game's focus remains stealth and infiltration, while retaining the series' self-referential, fourth wall-breaking sense of humor. Snake Eater ' s story is told through numerous cut scenes and radio conversations.
