Steaua București

Clubul Sportiv al Armatei Steaua București (Romanian pronunciation: [ˈste̯awa bukuˈreʃtʲ]), commonly known as Steaua București or simply Steaua, is a Romanian football club based in Bucharest and one of the sporting sections of CSA Steaua București.

In 2017, the parent club reactivated its football section and entered it into the 2017–18 season of Liga IV, the fourth tier of the Romanian Championship.

According to the club's records and the latest Romanian court orders (July 2019 and June 2021) it is the most successful football club in Romania, with national records for winning the domestic trophies, plus the European Cup in 1986 and European Super Cup in 1987. However, ownership of the titles is disputed between two entities, with agencies such as UEFA and LPF attributing all of the original club history to the other club, FCSB.

They play their home matches at the new Steaua Stadium. They used to play on Ghencea V between 2017 and 2021, one of the former training fields of the Complexul Sportiv Steaua, as the previous stadium, used by the historic Steaua entity during its heyday, was demolished in order for the current stadium to be built in the old one's place. The team colours are red and blue.

The club has a long-standing rivalry with neighbouring Dinamo București, with matches between the two being commonly referred to as "the Eternal Derby", "the Romanian Derby" or "the Great Derby".
