Clube Atlético Mineiro (Brazilian Portuguese: [ˈklubi atˈlɛtʃiku miˈnejɾu]), commonly known as Atlético Mineiro or Atlético, and colloquially as Galo (pronounced: [ˈgalu], "Rooster"), is a professional football club based in Belo Horizonte, Minas Gerais, Brazil. The team competes in the Campeonato Brasileiro Série A, the first level of Brazilian football, as well as in the Campeonato Mineiro, the top tier state league of Minas Gerais.
Atlético Mineiro is the oldest active football club in Minas Gerais, founded on 25 March 1908 by twenty-two students from Belo Horizonte. Despite having liberal, upper-class founders, the club opened its doors to players of every social class, establishing itself as a "people's club", and becoming one of the most supported in Brazil. The club's mascot, a rooster, has been strongly associated with Atlético since its introduction in the 1930s. Over the years, the word galo (Portuguese for "rooster") became a common nickname for the club itself. The team's regular home kit comprises black-and-white striped shirts, with black shorts and white socks.
Atlético has won the Campeonato Mineiro a record 43 times. At national level, the club has won the Campeonato Brasileiro once and has finished second on five occasions. Atlético has also won one Copa do Brasil, one Copa dos Campeões Estaduais and the Copa dos Campeões Brasileiros. In international club football, Atlético has won the Copa Libertadores and the Recopa Sudamericana once each, and a record two Copa CONMEBOL; the team has also reached three other continental finals. The club has also competed in other sports throughout its history, with the futsal department becoming especially notable.
The club plays the majority of its home matches at the Independência, while the Mineirão — the club's ground for most of its history — is used as Galo's home in important and high-attendance matches. Atlético has a long-standing cross-city rivalry with Cruzeiro, with matches between the two teams referred to as the Clássico Mineiro. The club also holds a local rivalry with América Mineiro, and an interstate one with Flamengo. Atlético has the eighth most valuable brand in Brazil, worth R$515.5 million (€143 million) as of 2016, and ranks seventh in the country in terms of turnover, generating R$244.6 million (€62.2 million) in 2015.
