A Head Full of Dreams is the seventh studio album by British rock band Coldplay, released on 4 December 2015, by Parlophone in the United Kingdom, and by Atlantic Records in the United States. Coldplay recorded the album from early to mid 2015, right after the completion of their previous album Ghost Stories, with a markedly different style and sound from its predecessors. For various songs, Coldplay collaborated with Beyoncé, Noel Gallagher, Tove Lo, Khatia Buniatishvili and Merry Clayton. The album was produced by Rik Simpson and Stargate. The album also features a sample of President Barack Obama singing "Amazing Grace" at Clementa C. Pinckney's funeral on the song "Kaleidoscope".

A Head Full of Dreams received generally mixed reviews from critics. Nevertheless, it was a commercial success as it topped the UK Albums Chart, and peaked at number two in the United States, Australia, Canada, and Italy, where it was held off the top spot by Adele's 25. At the 2016 Brit Awards the album was nominated for British Album of the Year. It was the eighth-best-selling album of 2015 with 1.9 million copies sold worldwide, according to the International Federation of the Phonographic Industry. It was the ninth-best-selling album of 2016, with 1.4 million copies sold worldwide, according to the International Federation of the Phonographic Industry. As of November 2017, the album has sold over 4.5 million copies worldwide. It was supported by five singles: "Adventure of a Lifetime", "Hymn for the Weekend", "Up&Up", the title track, and "Everglow". A 5.1 Surround Blu-ray Audio version of the album was released via the band's website on 23 September 2016.

The album was promoted by the successful A Head Full of Dreams Tour, that lasted nearly two years. The following year after the tour's conclusion, the band released Live in Buenos Aires, which was recorded on the final two nights of the tour in La Plata, Buenos Aires. A concert film and a documentary were also included in a deluxe edition of the CD. A second live album entitled Love In Tokyo was also released as a Japanese exclusive album which featured recordings from multiple legs of the tour.
