FC Petrolul Ploiești

Asociația Clubul Sportiv Petrolul 52, commonly referred to as FC Petrolul Ploiești (Romanian pronunciation: [peˈtrolul ploˈjeʃtʲ]), Petrolul Ploiești or simply Petrolul, is a Romanian professional football club based in Ploiești, Prahova County, that competes in the Liga I.

Founded in 1924 in capital Bucharest as Juventus, following the merger of Triumf and Romcomit, it won its first league championship in the 1929–30 season. In 1952, the team was relocated north to the industrial city of Ploiești, and five years later settled on the name of Petrolul. Shortly after, it achieved three more national titles—in 1957–58, 1958–59 and 1965–66. Domestically, its honours also include three national cups, the latest in the 2012–13 campaign.

Petrolul recorded its European debut in the 1958–59 season, when it was drawn against Wismut Karl Marx Stadt in the preliminary round of the European Cup. The club has participated in 12 editions of European competitions overall, of which eight governed by UEFA. In recent history, Petrolul became insolvent in February 2015 and dissolution followed the next year, however supporters and club legends promptly refounded and enrolled it in the fourth division.

The team colours are yellow and dark blue, hence the nickname of the players and fans being "the Yellow Wolves". Petrolul plays its home games at the 15,073-seater Ilie Oană Stadium, and its most notable rivalry is the one against Rapid București. Petrolul also had a local rivalry with Astra Giurgiu, which had been based in Ploiești until 2012.
