Isle Delfino is a tropical paradise island and vacation resort inhabited by Piantas, Nokis, Yoshis, Sunflower Kids, and Raccoons. Alongside the smaller Pinna Island, it resembles a dolphin, as indicated by its name, which means "dolphin" in Italian. This is a reference to the Nintendo GameCube's preproduction code name, Project Dolphin. Isle Delfino is the main setting of Super Mario Sunshine, and has since reappeared in many spin-offs, including the Mario Kart series.

Many of the locations on Isle Delfino can be clearly seen from some of the other locations on the island, with the exception of Noki Bay, which remains virtually hidden from the rest of the island, though small glimpses of it can be seen from the tops of some of the large palm trees in Pianta Village.

Super Mario Sunshine
Mario, Peach, Toadsworth and some Toads take a trip to Isle Delfino in Super Mario Sunshine. However, the island had been covered in graffiti by the mysterious Shadow Mario, who the people think is Mario. With the help of the water pack FLUDD, Mario is forced to get rid of all the paint on the island and clear his name by defeating the imposter that has been causing trouble. Shadow Mario turns out to be Bowser Jr., who soon kidnaps Peach, but after Mario defeats him and his father, Bowser, life on the island returns to normal and Mario, Peach and their friends enjoy the rest of their stay on Isle Delfino.

Mario Kart series
Isle Delfino has appeared in five of the Mario Kart games with new courses and stages based on it.

In Mario Kart: Double Dash!!, Peach Beach takes place on Isle Delfino. After the player completed the Grand Prix, the award ceremony was held there. Mario Kart DS features Delfino Square, which takes place in autumn instead of the usual tropical weather. In Mario Kart Wii, both Peach Beach and Delfino Square returned in the Retro cups, along with a new battle stage called Delfino Pier, which likely takes place in the docking area of Delfino Plaza. Additionally, Coconut Mall takes place on Isle Delfino, and returns in Mario Kart 7 as a retro track, as well as in Mario Kart 8 Deluxe as part of the Booster Course Pass.

Other games
Locations on Isle Delfino are shown in a couple of Mario Party minigames. Mario Power Tennis includes both the Delfino Plaza Court and the Gooper Blooper Court, which is set in Ricco Harbor.

Delfino Plaza is also one of the boards in Itadaki Street DS and Fortune Street. It is also one of the stages in Super Smash Bros. Brawl, Super Smash Bros. for Wii U and Super Smash Bros. Ultimate.

Economy
Like in the Mushroom Kingdom, Isle Delfino uses Gold Coins as currency. However, Isle Delfino may also use Blue and Red Coins as well.
