From the Super Mario Wiki
Star Cup is a representation of four to five courses in the Mario Kart series and its symbol is a Star. In Mario Kart: Double Dash!!, this cup is completed to unlock the Special Cup. This cup usually consists of courses that are better suited for Mario Kart veterans. There are more gimmicks, boost pads, and jumps here. The tracks are usually as long as the ones from Flower Cup.

Mario Tennis series
The Star Cup makes regular appearances in the Mario Tennis series. Usually, it is the third, last cup of the Open Tournament. When players clear the Star Cup, they receive a star ranking, which rewards them with stronger stats while allowing them to participate in the Special Tournaments. In Mario Tennis Open, however, the Star Cup is called the Final Cup, and it is the last cup of the Special Tournaments, making it the eighth and last cup. Meanwhile, the Champions Cup replaces the Star Cup as the fourth, last cup of the Open Tournament.
Super Mario Strikers
In Super Mario Strikers, the Star Cup has eight teams, seven rounds, and uses the table system. When the player finishes in the top three, the Bowser Cup and The Battle Dome are unlocked. A similar cup is the Super Star Cup.
Mario Sports Mix
The Star Cup also appeared in Mario Sports Mix as a harder difficulty, not unlike the other series. The Star Cup in Mario Sports Mix includes the final match against the Final Fantasy team and Behemoth or Behemoth King after the players have completed the cup. Star Road is also found on this cup, which is an alternate path available once players clear the Star Cup.
