São Paulo Futebol Clube (Brazilian Portuguese: [sɐ̃w ˈpawlu futʃiˈbɔw ˈklubi] ) is a professional football club in the Morumbi district of São Paulo, Brazil. It plays in Campeonato Paulista, São Paulo's premier state league and Campeonato Brasileiro Série A, the top tier of Brazilian football. Despite being primarily a football club, São Paulo competes in a wide variety of sports. Its home ground is the multipurpose 67,052-seater MorumBIS Stadium, the biggest private-owned field in Brazil. São Paulo is part of the Big Twelve of Brazilian football, South America’s biggest worldwide champion — with three world titles, along Boca Juniors, Peñarol, and Nacional — and one of the only two clubs that have never been relegated from Brazil's top division, the other being Flamengo.
Founded in 1930 from a merger between the Club Athletico Paulistano and the Associação Atlética das Palmeiras, the club has used its traditional home kit of a white shirt with two horizontal stripes (one red and one black), white shorts, and white socks since its inception; the color choice was made in honour of its parent-clubs primary colors, and also to represent the colors of the state of São Paulo. Although its main affiliation is with the state and city where it was founded, São Paulo is a national team and the third best-supported club in Brazil, with over 22 million supporters, covering around 9.9% of its population. Their supporters are called são-paulinos and are often nicknamed Torcida que conduz (Supporters who lead), due to their importance in maintaining São Paulo’s long lasting relevance in South America’s football. São Paulo ranked fifth in Brazil with a market value of R$ 2.214 billion in 2023.
