Delfino Plaza is the main hub of Isle Delfino, lying at the nose of the dolphin-shaped island. It is located at the foot of Corona Mountain. The plaza is named for the island it is located on. It is inhabited solely by Piantas and Nokis.
 Super Mario Sunshine
Delfino Plaza is the central location on Isle Delfino where Mario, Peach, and the Toads go to enjoy their vacation in Super Mario Sunshine. It is the largest city in the game, and features a few landmarks, including the Shine Gate and the Grand Pianta Statue. It also houses a lighthouse, a Boathouse, and multiple small fruit stands. The Piantas that inhabit Delfino Plaza rely heavily on the presence of the many Shine Sprites as a source of safety and comfort. However, after Shadow Mario polluted the island with toxic Graffiti, the Shine Sprites fled, casting Delfino Plaza into darkness. The island's inhabitants subesquently blamed Mario for the mess, and therefore tasked him with the cleaning of the entire island. After Mario chases and defeats Shadow Mario in Episode 7 of every level, Shadow Mario releases boiling water from Corona Mountain, flooding Delfino Plaza and forcing the citizens to retreat to their rooftops for safety.
Delfino Plaza also serves as the hub world of the game, as all seven main levels can be accessed from here, and Mario will return to the plaza after exiting a level as well. Bianco Hills, Ricco Harbor, and Gelato Beach can all be accessed via the Color Portals shaped like the letter "M." that are located on the Grand Pianta Statue, the Boathouse, and the lighthouse. Pinna Park can be accessed via a cannon on the west side of Delfino Plaza, and Noki Bay can be entered by staring at the sun while standing on a picture of a Shine Sprite. Sirena Beach and Pianta Village are both accessed by means of red Warp Pipes, which are located on a local rooftop and the Shine Gate . Once unlocked, Corona Mountain can be entered via a small cave directly behind the Shine Gate. After Corona Mountain is accessed at least once, even if Bowser has not yet been defeated, a boat will appear near the Boathouse, which will take Mario back to Delfino Airstrip for a 10-coin fare. As more Shine Sprites are collected (resulting in different events), the plaza will keep on getting brighter and brighter until they are all collected or Bowser is defeated.
Many secret levels and hidden Shine Sprites can also be found in various locations around Delfino Plaza. In addition, there is a large sewer system built directly under the town, which contains many coins, Blue Coins, and 1-Ups.

 Itadaki Street DS
In Tour Mode, the player has to claim 1st against Wario, Waluigi and Yoshi. Beating this board will unlock Waluigi.
 Fortune Street
Delfino Plaza makes a reapperance in Fortune Street. In Easy mode, the board looks like a heart with two circles on the bumps of the heart. In Standard mode, the board looks like three ovals that connect at the bank, which is in the center, making it resemble a 3 leafed clover. In Tour mode, the player has to get at least 2nd against Wario, Waluigi, and Luigi.
 Super Smash Bros. Brawl
Delfino Plaza appears as a stage in Super Smash Bros. Brawl. It takes place mostly in the skies of Delfino Plaza, on a set of floating platforms. However, not all gameplay is on the platforms; they frequently land in different areas of the Plaza, allowing a proper fight to take place. For example, the platform may land in front of where the Grand Pianta Statue should be. The platforms soon appear again and take the fighters to a different area.
Other places the platforms may land are as follows: on top of the Shine Gate, on the different sized pillars near the pipe to a secret level, outside the building containing the crate-smashing game, on the small island where a Pianta was looking for fruit, on the boat canal area, and on top of the house with the pipe leading to Sirena Beach. After the platform has been to every Delfino Plaza location, the platform will then return to the initial position, over the sea, before starting over and returning to the Plaza for another round. The order the places are visited is random.
A few minor adjustments to the city have been made. Perhaps the most noticeable are the disappearance of the Grand Pianta Statue and two platforms mounted on either side of the Shine Gate. These platforms were absent in Super Mario Sunshine, and were added specifically for the purpose of creating a place for a fight. Also, the Shine Sprite within the Shine Gate looks different from its Sunshine counterpart and also spins constantly, whereas it was immobile in Sunshine. Other differences include the absence of Piantas, the change in the appearance of various trees, and the disappearance of the red pipe to Sirena Beach. Just south of the location of the Grand Pianta Statue, there is a square-shaped extension of the stone dock that was absent in the original game. Finally, if one compares the sizes of Mario and/or Peach in Brawl to their sizes in Super Mario Sunshine, it is apparent that the entire plaza has been shrunk to the point where Mario appears larger.
 Themes in My Music
 Mario Power Tennis
A Delfino Plaza Court appears in Mario Power Tennis. If the player choses to play without gimmicks, the court has a zig-zag pattern with bright, neon colors. If the player plays with gimmicks, the court turns a greenish-blueish color with 3 circles that have Petey Piranha's face on them. If the ball touches the circle, a Polluted Piranha Plant will pop up out of the Goop next to the court and spit Goop on the circle. The Goop slows the player down, but it can be removed by stepping on the F.L.U.D.D. circle next to it.
 Mario & Sonic at the Sochi 2014 Olympic Winter Games
Delfino Plaza will appear in the upcoming Mario & Sonic at the Sochi 2014 Olympic Winter Games as a Dream Event for the Hockey event.
 Official Description
Tourists get off the ferries here, in Isle Delfino's largest city. Attractions include the Shine Gate and Grand Pianta Statue.
The music and theme of Delfino Plaza invokes Italian folk music. The melody alternates between guitar and accordion, while another guitar provides rhythm and an upright bass adds the pizzicato bassline. The melodies from Ricco Harbor, Gelato Beach, Bianco Hills, and The Staff Roll are all remixes of Delfino Plaza's melody and are all written by Koji Kondo.
