״The Box״ is a comprehensive five-CD and one-DVD box set by the American rock band Chicago, released through Rhino Records in 2003. The collection was authorized and curated by the band, including selections from their entire discography, spanning from their 1969 debut Chicago Transit Authority to their late 1990s recordings. It features material from every studio album and includes rarities such as three tracks from the unreleased 1993 Stone of Sisyphus project. The set encompasses every charting single from 1969 to 2003, excluding the 1986 remake of "25 or 6 to 4." The DVD contains rare live recordings from 1972 and promotional material for the 1979 album Chicago 13. Additionally, the box set includes a booklet with track-by-track analysis, promotional photos, essays, and variations on the Chicago logo. Despite its extensive content, the set did not chart in the US or the UK.
