Between Us is a greatest hits album by British girl group Little Mix, released on 12 November 2021 through RCA Records.

In 2021, it was one of Sony Music's top ten best-selling albums globally of that year and has been certified Platinum by the BPI, ARIA, IFPI, and Gold by RMNZ and AMPROFON.

[2] The album was made available in different versions, while the standard edition consists of Little Mix's biggest hits between 2011 and 2022, including four of their five UK number-one singles, "Wings", "Black Magic", "Shout Out to My Ex" and "Sweet Melody".

Their debut solo single "Cannonball", which peaked at number one in the UK, is featured on the CD deluxe edition as the final track.

Little Mix teased the project on 16 August 2021, three days before the official announcement, via their social media accounts by posting a video displaying all of their former logos, with a new one being shown at the end along with a snippet of one of the new songs, what would become the title track.

[7] The album was made available in a variety of physical formats, including on CD, cassette, as a box set and on picture disc vinyl with editions featuring each individual member in front of a floral backdrop.

[9] Group members Perrie Edwards, Jade Thirlwall and Leigh-Anne Pinnock went on to share their thoughts on the album.

On 15 November 2021, Little Mix released the Mixers Edition of Between Us on Spotify, after asking fans in October to choose the order of the existing album tracks and 10 new songs to include.

[16] It was received positive reviews from critics with Lyndsey Havens from Billboard describing the new song as the "punchy, soulful pop stompers that fans have come to crave from Little Mix".

Little Mix described the track as a tribute to their friendship, with lyrics that references to some of the group's previous released singles.

[21] The music video was released on 2 December 2021 alongside a message from the group announcing their hiatus after the Confetti Tour in 2022.

[22] Before the album was released, it was reported by Official Charts Company that at the midweek stage, Little Mix and Taylor Swift were contenders for the number-one spot.

By the end of 2021, Little Mix was named as one of three UK acts to be featured on the top-ten best selling albums from Sony Music Entertainment.
