Mario & Luigi: Superstar Saga (マリオ＆ルイージRPG Mario & Luigi RPG?) is the first game in the Mario & Luigi series released for the Game Boy Advance in 2003. It is one of the current six Mario role playing games.

Mario and Luigi went to save Princess Peach from the clutches of Cackletta and her evil assistant Fawful. This game takes place in the Beanbean Kingdom, a neighboring kingdom frequently visited by the members of the Mushroom Kingdom. The cartridge also included a port of Mario Bros., like the Super Mario Advance series. It was able to link up to the Super Mario Advance games for multiplayer. The game reused Mario's voice clips from Super Mario 64.

This game released in April 2014 on the Virtual Console along with Super Mario Advance 3: Yoshi's Island for the Wii U.

An updated remake for the Nintendo 3DS known as Mario & Luigi: Superstar Saga + Bowser's Minions was released on October 6, 2017.
