Collapse into Now is the fifteenth and final studio album by American alternative rock band R.E.M., released on March 7, 2011, on Warner Bros. Produced by Jacknife Lee, who previously worked with the band on Accelerate (2008), the album was preceded by the singles "It Happened Today", "Mine Smell Like Honey", "Überlin" and "Oh My Heart".

Regarding the album's title, lead singer Michael Stipe noted, "It's the final thing I sing, the last song on the record before the record goes into a coda and reprises the first song. In my head, it's like I'm addressing a nine-year-old and I'm saying, 'I come from a faraway place called the 20th century. And these are the values and these are the mistakes we've made and these are the triumphs. These are the things that we held in the highest esteem. These are the things to learn from."

As of September 2011, the album had sold 142,000 copies in the United States. At the time of the band's breakup, bassist Mike Mills noted that the album's lyrical content contained "indications" that the band were planning to split. In 2019, the band was more forthright on the hints they were making via the album: "That's the record where we put ourselves on the cover for the first time and I'm waving goodbye, and nobody got it," said Stipe in 2019. "We were saying, 'This is it, sayonara, we're out of here.'"

The band did not tour to support the album and therefore never performed any of the songs in concert, although Michael Stipe did play "Every Day Is Yours to Win" without R.E.M. for the Tibethouse Annual Benefit Concert.

In 2008, while touring in support of Accelerate, R.E.M. discussed the possibility of ending the band in the near future. Entering the studio with producer Jacknife Lee, the band began recording a final studio album, with the intention of "going out on a high note." Regarding these initial discussions, bassist Mike Mills stated, "We knew we had some decisions to make regarding our contract with Warner Bros. We had to make some decision about how to continue going forward as a recording unit, and if we still wanted to tour together. Oddly enough, I think that independently, we all arrived at the conclusion that this was such a great opportunity to walk away on our own terms, that we thought, 'Why not take advantage of it?'" Buck later would state that the final decision to end the band came when Stipe remarked that "I need to be away from this for a long time." Buck suggested "How about forever?" and they thus decided to break up.

Collapse into Now was recorded in four different cities: Berlin, Germany; Nashville, Tennessee; and New Orleans, Louisiana, with demoing taking place at Jackpot Studios in Portland, Oregon. Regarding the recording process, and the fact that it marked the conception of their final studio album, Mills noted, "We tried to enjoy it as much as possible and make it as fun as possible, but we’re not super-sentimental people in that sense. The only time we got really poignant was when we were working in Berlin, and they have a beautiful room there, Meistersaal, where we recorded seven or eight songs. There was no one there really except some friends, family, and significant others, and we knew that was probably the last time we would ever play together as R.E.M. That was a pretty fraught day. But it was fun."

In comparing the record to the band's previous release, Accelerate, Mills noted that the band, "wanted this new one to be more expansive. We wanted to put more variety into it and not limit ourselves to any one type of song. There are some really slow, beautiful songs; there are some nice, mid-tempo ones; and then there are three or four rockers." He has spoken about the album's theme, saying: "It's more of a personal record than a political one. Current events do come into our mind when we write, but the themes here are more universal."

The album has guest appearances by Patti Smith, Eddie Vedder, Peaches, Lenny Kaye, and Joel Gibb.
