Super Mario Party is a party video game developed by NDcube and published by Nintendo for the Nintendo Switch. The eleventh main instalment in the Mario Party series, it was released worldwide on 5 October 2018, and sold 1.5 million copies by the end of the month, making it one of the system's best-selling titles.

Super Mario Party reiterates traditional Mario Party-style gameplay, a format that's remained absent since 2007. The game is played with one Joy-Con controller per player, with other players needing additional controllers for multiplayer. The standard game mode, Party Mode, features up to four players taking turns and navigating the board in search of stars, with one located in a random location at a time. Upon the player's turn, a dice is rolled to determine how many spaces the player moves on the board, and items collected can be used to alter how many spaces the player can move. Each space has a unique function, such as blue and red give and take three coins respectively. If a player passes a star, they can spend ten coins to purchase it; whoever has the most coins at the end of the game wins. Coins can additionally be spent on items to give the player advantages. After each turn, the players compete in a minigame which awards coins based on their placement. Minigames vary with rules and function, such as the Trike Harder minigame, which uses motion controls.
