Peach Field is the third playable court in the Mushroom Tourney in the game Mario Hoops 3-on-3.
It looks like a grassy field on top of a large rocky plateau. There is an arch on either side that has the logos for Nintendo and Square Enix, past the baskets. What's interesting about this court is that Lakitu holds the basket on his fishing line. While he doesn't move, Lakitu and the basket will only appear if a character approaches the end of the court with the ball and only then if that basket is designated to that team. If one or more of these conditions are not met, Lakitu will not appear, preventing the player from scoring if they throw the ball from the other team's area. Also, Cheep-Cheeps bounce around and can be touched for an extra coin.
Peach Field can be seen in the background of Koopa Beach.
