Box Car Racer is the only studio album by American rock band Box Car Racer. Produced by Jerry Finn, the album was released on May 21, 2002, through MCA Records. The band was a side-project of Blink-182 members Tom DeLonge and Travis Barker, with David Kennedy completing the band's studio lineup. A bassist and friend of Barker, Anthony Celestino, later joined as the band's bassist after DeLonge recorded the bass tracks for the record.

The record is primarily based on DeLonge's post-hardcore influences, such as Fugazi and Refused. The recording sessions were particularly difficult for him, as he had recently undergone back surgery. The record is a concept album detailing the end of the world, and features dark, moody tracks mulling over confusion. Blink-182 bassist Mark Hoppus—the only member of that band not involved in the project—felt betrayed over his lack of inclusion, which evolved into tensions between him and DeLonge, which contributed to the band's 2005 breakup. Despite this, Hoppus provided guest vocals on the album's twelfth track "Elevator".

Box Car Racer peaked at number twelve on the US Billboard 200 despite little promotion, and the two singles "I Feel So" and "There Is" charted on Billboard's Modern Rock Tracks chart, with the former hitting the top 10. The album received positive reviews from music critics, who complimented the darker direction in comparison to DeLonge's previous work with Blink. The group toured the album in North America in late 2002 with the Used and H2O, and subsequently dissolved in 2003.
