Clássico dos Milhões

Clássico dos Milhões (English: Derby of the Millions) is the name given to Flamengo and Vasco da Gama association football derby, both teams from the city of Rio de Janeiro, Brazil. Considered one of the most fiercely contested derbies in Brazilian football, both in historic rivalry and in popularity. It has been named that way since its beginnings in the 1920s, as Flamengo and Vasco have the two largest fan bases in the state of Rio de Janeiro.

The derby is the fixture that has had an attendance of over 100,000 people the most times in the history of football, in addition to having the highest average attendance in the history of the Campeonato Brasileiro Série A. In addition, it is among the seventeen oldest derbies of Brazilian football, as its first match happened in April 1923.

Poll estimations, though variable, attribute Flamengo and Vasco two of the five largest Brazilian fanbases, usually with Flamengo at first and Vasco at fifth. At Rio de Janeiro state level, polls suggest that both clubs have the two largest declared supporter bases, with Flamengo at first in that matter.

Flamengo and Vasco have clashed in decisive and important matches in the Campeonato Carioca, Campeonato Brasileiro and Copa do Brasil, even deciding the finals of the latter in the 2006 edition.

Its intense rivalry, though more stressed in football since 1923 when Vasco rose to first division, started already in the prior decades in rowing regatte, as both clubs were founded in the late 19th century (Vasco 1898 and Flamengo 1895) as rowing clubs. Both teams also compete often at national level in other sports such as basketball, swimming, futsal and judo.
