Fotbal Club CFR 1907 Cluj, commonly known as CFR Cluj (Romanian pronunciation: [t͡ʃefeˌre ˈkluʒ] or [ˌt͡ʃefere ˈkluʒ]) or simply CFR, is a Romanian professional football club based in the city of Cluj-Napoca, Cluj County, that competes in the Liga I. Founded as Kolozsvári Vasutas Sport Club in 1907, when Transylvania was part of Austria-Hungary, the club's current name is an acronym for Căile Ferate Române ("Romanian Railways").

Before its promotion to Liga I in 2004, CFR Cluj primarily competed in the lower divisions. Since then, the club has increasingly relied on foreign players to achieve success. In the 2005–06 season, CFR participated in its first European competition, the Intertoto Cup, finishing as runners-up. With substantial financial backing from former owner Árpád Pászkány, the club won its first national championship in the 2007–08 season, ending a 17-year dominance by capital-based teams.

Between 2017 and 2022, "the White and Burgundies" won five consecutive Liga I championships. The club has secured 17 domestic trophies, all in the 21st century: eight Liga I titles, five Cupa României, and four Supercupa României. In addition to becoming a prominent force in Romanian football, CFR qualified three times each for the UEFA Champions League and Europa League group stages, and twice for the Europa Conference League group stages.

CFR shares a fierce rivalry with local club Universitatea Cluj, with their matches known as Derbiul Clujului. In recent years, the club has also developed less intense rivalries, notably with FCSB, as they frequently compete for the Liga I title.
