All We Know Is Falling is the debut studio album by the American rock band Paramore, released on July 26, 2005, under the Atlantic-distributed Fueled by Ramen in the United States. Its production was handled by James Paul Wisner, Mike Green, Nick Trevisick, and Roger Alan Nichols. The departure of bassist Jeremy Davis, which occurred a few days after arriving in Orlando, served as the album's main theme. This theme was reflected especially in the album's cover and title. Mostly categorized as a pop-punk album, the album received mostly positive reviews and has been labeled a "scene classic".

The album's production took place in Orlando, Florida. Instead of making a major push towards radio, the band's A&R recommended that the band build a fanbase through word of mouth. Initially, the album received positive reviews by music critics, praising the vocals of lead singer Hayley Williams; retrospective assessments have been more mixed. The album had a weak domestic commercial performance: it failed to enter the Billboard 200, though it did reach number 30 on Billboard's Heatseekers Chart. It reached No. 4 on the UK Rock Chart, and in 2010 it managed to reach No. 51 on the UK Albums Chart and earned a gold certification by the British Phonographic Industry (BPI). In July 2014, after the group found success with its following records, All We Know Is Falling received a gold certification from the Recording Industry Association of America (RIAA). Three singles from the album were released: "Pressure", "Emergency" and "All We Know". None of the singles managed to reach any major chart, although "Pressure" was certified gold by the RIAA in 2016 after the band found commercial success with subsequent releases.

Hayley Williams was originally signed to Atlantic Records in 2003 as a solo pop singer. However, Williams ultimately decided not to pursue a solo career, saying she did not envision herself as "the next Madonna". Instead, she recruited three friends, Josh Farro, Zac Farro, and Jeremy Davis, to form Paramore and convinced Atlantic to let them keep her contract if they could record some satisfactory demos. In her short solo career, Williams had already recorded some of her own demos, which were then re-recorded with the band for a "more authentic" sound. However, the band was almost fired because the label thought the finished demos "were terrible." Williams and Farro quickly wrote two new radio-friendly songs, "Here We Go Again" and "Hallelujah" in a compromise to save the album. The former song became the fifth track on All We Know Is Falling, while "Hallelujah" was saved for their sophomore album Riot! (2007).

The group traveled to Orlando, Florida, to write and record the remainder of the album. A few days after arriving in Orlando, Davis unexpectedly left the band. Williams and the Farros decided to continue on as a three-member lineup. They also decided to build the album's theme around their feelings toward Davis' departure. According to Williams, the album's cover art also represented Davis' departure: "The couch with no one there and the shadow walking away; it's all about Jeremy leaving us and us feeling like there's an empty space." The album's artwork was created by Electric Heat.

The album's recording process took about three weeks, with Josh Farro calling the sessions "rushed". "All We Know", "Never Let This Go" and "My Heart" were recorded with producer James Paul Wisner at Wisner Productions, located in St. Cloud, Florida. "Pressure", "Emergency", "Brighter", "Whoa", "Conspiracy" and "Franklin" were recorded with producer Mike Green at ARS Studios, located in Orlando, Florida. "Here We Go Again" was recorded with producers Roger Alan Nichols and Nick Trevisick at Bigger Dog Studio, located in Franklin, Tennessee. Additional recording took place at Stone Gables Studio, located in Brentwood, Tennessee and at The Skyview Church of Tone and Soul, located in East Nashville, Tennessee.

All of the songs were mixed by Green, except for "Here We Go Again", which was mixed by Nichols and Trevisick. Tom Baker mastered the recordings at Precision Mastering in Hollywood, California. Nath Warshowsky acted as the studio drum tech for every song, except for "Here We Go Again". Dave Buchman engineered "Here We Go Again". Lucio Rubino, then frontman of StorySide:B, replaced the absent Davis in the studio. He performed bass on every song except for "Here We Go Again", which was done by Jeremy Davis.

Typically, Farro would write the music while Williams wrote the lyrics. On occasion, Farro would contribute lyrics as well. "Conspiracy" was composed by Williams, Farro, and Taylor York. It was the first song they wrote together. Many of the lyrics in All We Know Is Falling which are not related to Davis' departure deal with the bad relationship and divorce of Williams' parents. While the song "Brighter" was written about Hayley's friend Lanie Kealhofer, who died on May 22, 2005. The album's liners included the following line: "In memory of Lanie Kealhofer – You shine brighter than anyone – 11.24.88 / 5.22.05".

Critics have variously called All We Know Is Falling a pop-punk, emo, pop rock, and alternative rock album. Trevor Kelley at Alternative Press categorized the album as "vaguely emo, but mostly mall-punk". Tom Whitson of Click Music defined the album as emo with "pop-punk beats", drawing comparisons from Avril Lavigne and Fall Out Boy. The Allmusic review by Neil Z. Yeung referred to the album as a "formulaic" pop punk album, complete with "head-bobbing drums, straightforward riffs, and a midtempo sameness throughout". In a retrospective Alternative Press review by Tyler Sharp, the album was referred to as what would have been "just another pop-rock effort that ultimately fell short in the face of its true potential" if not for the band's later success. Gigwise reviewer David Renshaw also drew comparisons to Lavigne, but believed that the songs on the album were inferior to those of Lavigne's.
