Mario Golf is a sports game that was developed by Camelot Software Planning. It was published by Nintendo for the Game Boy Color in 1999. In Japan, the Game Boy Color version is known as Mario Golf GB (マリオゴルフGB). It also provides the capability to interact with its Nintendo 64 counterpart. It was released four months after the Nintendo 64 version.

Though this game has the exact same name and a similar cover as its 64-bit predecessor, it has many variations. Camelot made a normal mode of golfing, similar to that of the Nintendo 64 version, in which the player chooses one of four characters to conquer the challenges of the golf world. However, the developer also included a new, more-involved mode of gameplay.

This new mode of gameplay had traits similar to that of a Role Playing Game. The player was granted the ability to control his or her character more freely. This game mode allowed much character interaction and environmental exploration, making this game have a slightly more detailed story than those in the rest of the series. The player could also Level Up, allowing characters to be more successful at golfing.
