Lethal Enforcers II: Gun Fighters, known in Japan as Lethal Enforcers 2: The Western, is a 1994 light gun shooter arcade game and prequel to the original Lethal Enforcers. In contrast with the first game's modern law enforcement theme, Lethal Enforcers II takes place in the American Old West.

Ports of the game were released for the Sega Genesis/Mega Drive and the Sega CD. The game was bundled along with the first Lethal Enforcers game as part of the PlayStation compilation Lethal Enforcers I & II. A Super NES version of the game was also announced that same year, but was cancelled for unknown reasons.

In this game, the goal is to shoot outlaws in order to eradicate crime from a stereotypical town in the American West of 1873. At the beginning of the game, three to five life units are available. In the arcade version, more can be purchased by inserting additional coins. Life units are also awarded based on how many points the player scores while playing the game. Every time the player, an innocent civilian or lawman is shot, one life unit will be lost. The game overs when all life units are gone, but continued play is available.

Lethal Enforcers 2 has five stages: "The Bank Robbery", "The Stage-Holdup", "Saloon Showdown", "The Train Robbery", and "The Hide-Out". During each stage, the player must shoot the armed outlaws without harming any innocent townsfolk or fellow lawmen. One shot is enough to kill most enemies. Each stage features a boss that must be killed in order to complete the stage (though a unique case happened in the third stage where the boss battle is in the form of a dueling mini-game). Just like the original game, a dip switch setting in the arcade version allows operators to let players progress through the stages in a linear fashion ("arcade mode") or select individual stages ("street mode"), including the between level target practice stages.
