Fluminense FC

Fluminense Football Club is a Brazilian sports club based in neighbourhood of Laranjeiras, in Rio de Janeiro, being the oldest football club in the state since its foundation in 1902. It competes in the Campeonato Brasileiro Série A, the first tier of Brazilian football, and the Campeonato Carioca, the state league of Rio de Janeiro. The word "fluminense" is the gentilic given to people born in the state of Rio de Janeiro, in Brazil.

Fluminense have been crowned national league champions four times, most recently in the 2012 Campeonato Brasileiro Série A; the team have also won the 2007 Copa do Brasil. In 1949, Fluminense became the only football club in the world to receive the Olympic Cup, awarded annually by the International Olympic Committee to an institution or association with a record of merit and integrity in actively developing the Olympic Movement. Its best international performances include winning the 2023 Copa Libertadores, winning the 1952 Copa Rio, and reaching the 2023 FIFA Club World Cup final.

Fluminense's traditional home kit consists of an iconic combination of three colors: burgundy, white, and green, disposed in vertical stripes, since its adoption in 1904. White shorts and white socks, an outfit which has been in use since 1920, complement the home kit for O Tricolor.

The club holds several long-standing rivalries with other clubs, most notably with Flamengo (Clássico Fla-Flu), Botafogo (Clássico Vovô) and Vasco da Gama (Clássico dos Gigantes). The Clássico Fla-Flu in particular is widely considered one of the greatest football derbies in Brazil and South America, having eventually set the world record for the highest attendance in a match between football clubs (over 200,000 spectators in the stadium of Maracanã).
