Punch-Out!! (パンチアウト!!, Panchiauto!!), originally released in North America as Mike Tyson's Punch-Out!!, is a boxing sports fighting video game for the Nintendo Entertainment System (NES) developed and published by Nintendo in 1987. It is a port of both the Punch-Out!! and Super Punch-Out!! arcade games (mostly the latter) with some variations. It has consistently been ranked among the best games released for the NES platform.Mario makes an appearance as the game's referee.

Punch-Out!! features a boxer known as Little Mac working his way up the professional boxing circuits, facing a series of colorful, fictional boxers, leading to a final fight with real-life boxer, the then-World Heavyweight Champion, which is Mike Tyson in the original version and Mr. Dream in the later version.

Little Mac has a limited repertoire compared to most of his opponents. His punches are limited to left and right jabs, left and right body blows, and a powerful uppercut. The uppercut can only be used once the player earns a star, which is typically accomplished by counter-punching the opponent directly before or after certain attacks are launched. The player can acquire up to three stars. To perform the powerful uppercut the player needs to press the start button once a star is earned. For defensive techniques, Mac can dodge left or right, duck, and block attacks.

Little Mac also has a heart meter, which decreases by three upon being struck by an opponent and one upon blocking an attack or an opponent blocking/dodging the player's attack. When the heart meter decreases to zero, Little Mac temporarily turns pink and appears exhausted, leaving the player unable to attack, but still able to defend. At this point, Mac can regain some hearts (and his normal color palette) only by avoiding the opponent's punches.

A bout can end by knockout (KO), if a fighter is unable to get up within ten seconds after being knocked down; by technical knockout (TKO), if a fighter is knocked down three times in one round; or by decision, if the bout lasts three full rounds without a clear winner. In order to win by decision, the player must accumulate a high enough point total by punching the opponent and/or knocking him down. However, some bouts cannot be won in this manner and will automatically result in a loss for the player if the opponent is not knocked out.

When Little Mac loses his first bout to a ranked opponent, he will have a chance to fight a rematch. However if he loses a Title Bout, he will fall one or more places in the rankings. Losing a rematch causes him to fall one place (unless he is already at the bottom of his circuit), forcing him to fight his way back up. A third loss (not necessarily a consecutive one) ends the game. The exception is the final fight against Mike Tyson/Mr. Dream; a loss to them automatically results in a game over.
