Club de Deportes Unión San Felipe, commonly known as Unión San Felipe or simply San Felipe, is a professional football club based in the city of San Felipe, in the Valparaíso Region of Chile. Founded on October 16, 1956, the club currently competes in the Primera B, the second tier of the Chilean football league system.
Unión San Felipe is best known for its historic ascent in the early 1970s, when it became the only club in Chilean football history to win the second division (1970) and the first division in consecutive seasons—claiming the Primera División de Chile title in 1971, just a year after earning promotion. That triumph earned them a place in the 1972 Copa Libertadores, marking their debut on the continental stage.
The club has also won the Primera B championship twice (1970 and 2009) and lifted the Copa Chile in 2009, qualifying for the 2010 Copa Sudamericana. San Felipe's home ground is the Estadio Municipal de San Felipe, a traditional venue with a capacity of approximately 12,000 spectators.
Nicknamed «El Uni-Uni», the club is renowned for its provincial identity, strong local fanbase, and historic role in breaking the dominance of Chile’s major urban teams in early 1970s.
