克里科

Curicó Unido was founded on 26 February 1973, with Edmundo Rojas as the first President of the club. They became the fourth football team from the Curicó city to play at the professional level, after Alianza de Curicó, Luis Cruz Martínez and Bádminton de Curicó.

Curicó Unido played since the season 1974 at the Primera B, but after seven poor seasons they gained relegation to the third level to the season 1981, returning to Primera B two years later, in 1983.

1984 and 1985 were the best seasons of Curicó Unido history, disputing the promotion until the last week, but with bad luck at the final matches.

The next campaigns were average, with the exception of the season 1990, when they lose the category after the final match with Deportes Valdivia, when they won 4–1, two goals short what they needed to stay at Primera B.

Since then, they stayed at the Tercera División without real chances to return to the Primera B, until the 2003 season. But at the next year that changed.

In 2004 the albirrojos were really close to return to the Primera B. At the last week of the season, in Chillán, they arrived as leaders, to face Ñublense who was three points behind at the table; however the Chillanejos won that game 2–1, forcing a tie breaker match in Linares, where Ñublense won 2–0, taking the title and the promotion.

However, the year 2005 Curicó Unido had his revenge. They disputed the title with Trasandino until the last week. While Trasandino tied with Municipal Iquique, Curicó crushed Iberia 4–0, and in this way, after 15 years of suffering, Provincial Curicó Unido returned to the Chilean professional football.

In 2006, in their return to the Primera B, Curicó Unido finished in fifth place.

The next year, Curico avoided relegation only at the end of the season; Deportes Temuco finished last and fell down to the third level of national football for the upcoming season.

Curicó won promotion to the Primera Division after a 1–0 win over Deportes Puerto Montt on the last home game of the 2008 season, which was enough to securing 1st place of the Primera B and automatic promotion. Only to return to Primera B the next season, after losing a promotion play-off against San Luis.

They returned to the top-tier in 2017, after winning the 2016–17 Primera B tournament.
