- “The castle you see from here was once a beautiful castle called Rainbow Castle. But the rainbow disappeared, and even the name Rainbow Castle has been forgotten. With your own hands, you must reveal the shining Rainbow Castle once more!”
- —Koopa Troopa, Mario Party
Mario's Rainbow Castle is Mario's game board in Mario Party. It is heavily based off of Tower of the Wing Cap and Wing Mario Over the Rainbow from Super Mario 64. The cloudy board looks visually appealing to begin with, but players need to collect Stars to restore the great rainbow of the castle. The board is a one-way path to the middle of the board (with 2 junctions). Players who make it to the center ride Fwoosh up to the tower, where either Toad or Bowser wait. Toad doles out the Stars as usual, but if players reach Bowser, he awards them with a Ztar at the cost of 40 coins (which will not add to their Star total). After getting either Star, the tower switches, replacing Toad with Bowser and vice versa, and Lakitu takes the player back to start. The Happening Space can be used to force the tower to turn around before a player reaches it.
At the end of the game, the winner's Stars form a large Star that makes a magnificent series of rainbows across the board, followed by a rainbow path from Fwoosh's center platform. The winner, as well as the players in 2nd and 3rd place go up the rainbow path to celebrate the victory along with Toad, Koopa, Boo, Fwoosh, and the Star. The player in 4th place attempts to travel up the rainbow too, but slips, falls, and is carried away by Lakitu.
One thing notable is that despite being Mario's board, Mario's Rainbow Castle is not the first board of the game.

Trivia
- This is the only board in the game designed in a traditional start-to-finish style board map while the others go all-around before the players meet up with Koopa Troopa.
