Just Dance 2018 is a 2017 dance rhythm game developed and published by Ubisoft. It was unveiled on June 12, 2017, during its E3 press conference as the ninth main installment of the series,^[1] and was released in October 2017 for PlayStation 3, PlayStation 4, Xbox 360, Xbox One, Wii, Wii U, and Nintendo Switch. This was the last Just Dance game to be released on the PlayStation 3 console, and by extension, the final PlayStation 3 video game to be published by Ubisoft.

As with the previous installments of the franchise, players must mimic the on-screen dancer's choreography to a chosen song using either motion controllers (Wii Remotes on Wii and Wii U, PlayStation Move on PlayStation 3, PlayStation Camera on PlayStation 4, Kinect on Xbox 360 and One and Joy-Con on Nintendo Switch) or the game's associated Just Dance Controller app on a smartphone.

While the Wii, PS3, and Xbox 360 versions of the game are based on Just Dance 2015, the current-generation console versions feature an updated user interface, which removed other additional modes except for the "World Dance Floor" to more focus on standard gameplay. In the "Just Dance" mode menu, players can activate Sweat by pressing a certain button on the controller.^[2] A new "Super" judgment was added between "Good" and "Perfect", as well as a "Megastar" rank, achievable at 12,000 points.^[2] The new "Dance Lab" mode, serving as a spiritual successor to the "Just Dance Machine" mode in Just Dance 2017, using the same scoring mechanic from that said mode, now with the addition of the traditional star ranking system, features medleys of choreography representing different professions and animals,^[2] while a new "Kids Mode" was designed to provide a gameplay experience and choreography tailored towards younger players, featuring a revamped scoring mechanic based on the traditional mechanic, with rainbow stars as the max rank, as akin to the "Superstar" rank in the main "Just Dance" mode, in which can also be played in that said mode with the traditional gameplay via searching.^[2]

The "World Dance Floor" mode has a revamped Team Battle feature, which players are randomly assigned to either the Red Team or the Blue Team, as well as seasonal rankings.

A new feature, "Gift Machine", based on the Crank-a-Kai feature in Yo-kai Watch Dance: Just Dance Special Version, was added. Using 100 Mojo points will allow the ability to unlock avatars, stickers, skins, alternate routines, "Dance Lab" episodes, and additional Mojo points.

The Nintendo Switch version of the game features an exclusive "Double Rumble" mode, which uses features routines based on different professions that leverage the "HD Rumble" functionality in the console's Joy-Con controllers to provide feedback.^[2] "Double Rumble" routines require two Joy-Con controllers to play. Furthermore, the "Beat Vibrations" option was also added to the Switch version, which allows Joy-Con controllers vibrate to the beat.

The Ubisoft Connect feature was removed in the PS3, and Xbox 360 versions of the game. Furthermore, the Community Remix and Mashup features were also removed.

All online services of the game for the Wii, PS3, and Xbox 360 versions were discontinued on November 19, 2018,^[3] followed by all other platforms on July 3, 2023.^[4]
