Just Dance 2017 is a 2016 dance video game developed and published by Ubisoft. It was unveiled on June 13, 2016, during its E3 press conference as the eighth main installment of the series,^[1] and was released in October 2016 for PlayStation 3, PlayStation 4, Xbox 360, Xbox One, Wii, Wii U, and Windows; and on March 3, 2017, for Nintendo Switch. The game was the only title of the series to be released on Windows, and was released as a launch title for Nintendo Switch.

As in previous installments, players must mimic the routine of an on-screen dancer to a chosen song, scoring points based on their accuracy. For input, the game supports either the respective motion controller system for a particular console platform (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 a smartphone with the game's companion mobile app.^[2] For the PC version, a gamepad and a keyboard can also be used for menu navigation. The Chinese version of the game removes online features, such as Just Dance Unlimited and the World Dance Floor.

The "Dance Party" mode has been renamed to the "Just Dance" mode, players can now have the ability to search for a song using the menu. The "Superstar" rank has been added, in which it's achievable at 11,000 points. A new "Just Dance Machine" mode was added on current-generation console and PC versions, in which players must dance through routines of different styles to help recharge an alien spaceship, using a unique scoring mechanic which shows green if successfully or red if messing up.^[2][3][4] Each session contains five routines, with "Cosmic Rounds" popping up randomly. The story of this mode follows two aliens that are dancing on their ship. All of a sudden, their battery is running low. To recharge its battery, the aliens travelled to Earth and abduct human dancers known as "coaches" to recharge its battery by dancing. In the ending, the battery was charged and the aliens leave Earth as they keep dancing. But unfortunately, their battery is running low once again.

Furthermore, the Wii U version doesn't have the ability to apply effects for "Autodance" videos, just like in previous entries.

All online services of the game were discontinued for the Wii, PS3, and Xbox 360 versions on November 19, 2018,^[5] followed by all other platforms on July 3, 2023.^[6]

The following songs appear on Just Dance 2017:

Note: "In the Hall of the Pixel King" by Dancing Bros. (based on "In the Hall of the Mountain King", written by Edvard Grieg, and "Ode to Joy", written by Ludwig van Beethoven) and "Itsy Bitsy Teenie Weenie Yellow Polkadot Bikini" by Brian Hyland (covered by The Sunlight Shakers) were planned to appear in the game, but they were scrapped for unknown reasons. They were later brought back to Just Dance 2018.

Steve Hannley of Hardcore Gamer thought that although Ubisoft had defied his prediction that Just Dance Unlimited would be the future of the franchise instead of physical releases, they had put a larger effort into the on-disc content of 2017 than 2016 (which he described as being a "last minute afterthought" to introduce Unlimited). The Just Dance Machine mode was considered to be "pointless" due to being a basic concept driven by its presentation, but is "a concept that's never been done before in rhythm games and an example of the innovation the series needs to warrant another physical release". Hannley also praised the higher quality of the game's soundtrack, including more recent hit music, fewer "joke" songs, and surfacing Gigi Rowe's "impressive" debut single "Run the Night". In conclusion, Hannley continued to assert that Ubisoft should focus more on providing more immediate access to recent music rather than requiring players to wait for the next annual physical release, but that Just Dance 2017 was "thankfully a marked improvement over its predecessor."^[4]
