WarioWare: Get It Together! is a 2021 party video game developed by Intelligent Systems and published by Nintendo for the Nintendo Switch. The 11th installment in the WarioWare series, succeeding WarioWare Gold (2018) for the Nintendo 3DS, the game was released worldwide on September 10, 2021. and sold 1.34 million copies worldwide. It is the final game in the WarioWare series to feature Charles Martinet as the voice of Wario before his retirement from voicing the character (and other characters in the Mario series) in 2023.

WarioWare: Get It Together! received generally positive reviews from critics and was nominated for "Best Family Game" at The Game Awards 2021, as well as "Family Game of the Year" at the 25th Annual D.I.C.E. Awards. As of December 2022, the game had sold more than 1.34 million units worldwide, making it the 83rd-best-selling game for the Nintendo Switch. WarioWare: Get It Together! was succeeded by WarioWare: Move It!, a 2023 title also released for the Switch.

Get It Together! continues the WarioWare series tradition of tasking players with completing sets of "microgames", which each require the player to clear an objective in just a few seconds. In this game, Wario and his friends have been sucked inside his latest gaming device, meaning they must participate in the microgames themselves.

As such, the game has up to two players control a group of characters, randomly alternating between them in between Microgames. Characters are controlled using the directional stick and a single button, with each character behaving differently in how they move and what actions they can do. For example, Wario flies around on a jetpack and can perform a shoulder charge, Mona alternates between automatically riding her scooter and controlling a boomerang in the air, and 18-Volt fires CDs from a stationary position and can only move around by hooking onto rings. These unique abilities mean each character has different ways of clearing the same microgame. For example, a microgame that requires spinning a windmill around can be cleared by either pushing the windmill physically or hitting it with projectiles. Up to 20 different characters can be unlocked for selection. In each stage, microgames appear consecutively, presenting the player with a simple prompt with which to clear the microgame. Failing a microgame, either by losing the game or running out of time, one of four lives will be deducted, with the stage ending once the player runs out of lives.

There are party-style minigames for up to four players outside of story mode. There is also a ranked mode in the game called the Wario Cup featuring various different challenges.

The player can give presents (named prezzies in-game) to the various playable characters to level them up. Leveling up a character will result in the base score being raised in which can benefit the player in the Wario Cup. The player will also be able to customize the appearance of the playable character of choice. Prezzies can be obtained in the emporium and by other means.

The game begins with Wario and his friends at his company WarioWare Inc. (which includes Lulu, who previously appeared in WarioWare: Gold) when Wario finishes the game unit they have been developing. When he tries to start it, the console does not turn on, much to Wario and his friends' confusion. Annoyed, Wario tosses the console in the air and he, along with his friends, is sucked into the game as a virtual version of himself. When they wake up, they discover that their game has been invaded by "Game Bugs", which cause corruption and glitches within the game's levels. Wario and his friends have to defeat these bugs to clean the game and return to the real world.

Eventually, the group defeat the game's final bug, the Wario Bug, a corrupted and possessed version of Wario. They then leave the game bugs alone after Wario gives the bugs a home in the final level. "The Supreme Developer", a god-like figure with Wario's nose and mustache, appears to them after that and tells them that he brought Wario and his friends into the game to clear it of the game bugs, which Wario inadvertently caused due to his poor programming skills. He then tells the group that they are free to go. Back outside, everyone learns of Wario's involvement in developing the game bugs and angrily chase him down, but he notices that three of WarioWare's members (Red, Master Mantis and Lulu) are still stuck in the game, and the group goes back into the game to find them.
