Sport Club Corinthians Paulista (Brazilian Portuguese: [isˈpɔɾtʃi ˈklubi koˈɾĩtʃɐ̃s pawˈlistɐ] (listen)) is a Brazilian sports club based in the Tatuapé district of São Paulo. Although competing in a number of different sports, Corinthians is mostly known for its professional association football team that plays in the Campeonato Brasileiro Série A, the top tier of the Brazilian football, as well as in the Campeonato Paulista Série A1, the first division of the traditional in-state competition.

Founded in 1910 by five railway workers inspired by the London-based Corinthian Football Club, Corinthians has become one of the most successful Brazilian clubs, having won the national title seven times, in addition to three Copa do Brasil trophies, one Supercopa do Brasil and a record 30 São Paulo State championships. On the international stage, the club won the inaugural FIFA Club World Championship in 2000, winning it for the second time in 2012 after being crowned Copa Libertadores de América champions for the first time that same year.

The club's home kit traditionally features white shirts and black shorts, accompanied by white socks. Their traditional crest was introduced in 1939 by modernist painter Francisco Rebolo featuring the São Paulo state flag in a shield, two oars, and an anchor representing the club's early success in nautical sports. Since 2014, Corinthians has played its home matches at the Arena Corinthians, one of the venues in the 2014 FIFA World Cup, having hosted the opener on 12 June 2014 and a total of six matches during the tournament.

The club was listed by Forbes in 2017 as the most valuable football club in the Americas, worth $576.9 million. The club is one of the most widely supported teams in the world and the second most in Brazil, with over 30 million fans.
