Esporte Clube São Bernardo

Esporte Clube São Bernardo, commonly known as EC São Bernardo, Esporte Clube, or Esporte, is a professional football club based in São Bernardo do Campo, São Paulo, Brazil, that plays in the Campeonato Paulista Série A3, the third tier of the São Paulo state league. They were founded in 1928, being the oldest active football club in the ABC Region. They also were the first basketball club in the city (achieving great prominence), as well as in volleyball and futsal.

Despite being based in one of the richest and most populous cities in São Paulo, the club has never been successful at the state level, having spent most of its years in the lower divisions of the Campeonato Paulista and has yet to qualify for any national division. Their highest state league finish was in the 1986 Campeonato Paulista Segunda Divisão, when they finished 3rd in the table, nearly missing promotion for the premier division.

During the 1990s, the club often escaped relegation due to other clubs folding or not meeting the criteria for promotion in upper levels. This and a win drought that lasted over a year brought nationwide attention to the club, which at the time was regarded as the worst performing team in Brazil.

They have a long-standing rivalry with Palestra, with whom they contest the Clássico Batateiro.
