Unión La Calera is a Chilean football club based in La Calera, Chile. The club competes in the Primera División de Chile.
It was founded as Club de Deportes La Calera on 26 January 1954, after the merger of three teams from the city: Condor, Calera Comercio and Tifón. The following year, Deportes La Calera joined Club de Deportes Melón (originated by the merger between Cemento Melón and Minas Navío) to form Unión La Calera.
After spending 6 seasons in the second division, the club obtained its first promotion to Primera División de Chile in 1961, where they remained until 1974. In 1985, they returned to top-tier, but they were relegated the incoming season. From there, they wandered through second division and third division, until returning to the top category in 2011, and in 2018, after a brief stint in the promotion division (Primera B). Unión La Calera has won three second division titles (the 1961 and 1984 Segunda División de Chile titles; and a 2017 Primera B title) and two Tercera División de Chile honors (1990 and 2000).
The color that identifies the club is red (present in their uniform since the formation as Union La Calera) and disputes their home games at the Nicolás Chahuán Nazar Municipal Stadium. Nevertheless, due to its reconstruction, around 2017 and 2018 they moved to Estadio Municipal Lucio Fariña Fernández in neighboring Quillota (which has a capacity for 7703 spectators).

History
1954–1970: Beginnings
The club was founded on 15 April 1955. It was following the merger between five local clubs: Tifón, Minas Navío, Cóndor, Cemento Melón and Calera Comercio. Nevertheless, the club's foundation was recorded on 26 January 1954.
2011–2016: Primera División de Chile
Unión La Calera began the 2011 season hiring eight players: Jonathan Domínguez (forward from Unión San Felipe), Rodrigo Flores (goalkeeper from O'Higgins), Ángel Carreño (midfielder from Deportes La Serena), Jorge Ampuero (defender from Unión Española), Ramón Ignacio Fernández (from Argentinian powerhouse Estudiantes de La Plata), Braian Rodríguez (from Peru's top-tier Club Deportivo Universidad de San Martín de Porres), Claudio Muñoz (from Universidad de Concepción) and Luis Jiménez Barrera (from Deportes Melipilla).
They debuted in the 2011 Torneo Apertura on 30 January with a 1–1 draw with Santiago Morning. In this match the scores were from Paraguayan striker Ever Cantero for Santiago Morning and an own-goal from Edgardo Abdala. The next week on 6 February, the Uruguayan Braian Rodríguez (the striker from San Martín de Porres) scored Calera's first goal in top-tier in a 1–0 home win over Unión San Felipe. Besides, it was the club's first goal scored by a team's player after its 24 year-absence in Primera from 1987 season (considering Abdala's own goal). On 12 February, for the third week, they surprised everyone after beating 2–1 to Universidad Católica as local in Nicolás Chahuán Nazar Municipal Stadium. The goals for Calera were scored by the defender Claudio Muñoz in the 39th minute (who precisely played in Universidad Católica between 2004 and 2007, prior to play in Universidad de Concepción) and Diego Cuéllar in the 75th minute, who netted the tie-breaker goal after Hans Martínez's equalizing goal in 66th minute. Thereby, Unión La Calera broke the small unbeaten Universidad Católica had in the first two games (a 0–2 away win over Deportes Iquique and a 3–1 victory against Audax Italiano). Nevertheless, on 19 February, now Calera's short unbeaten was broken by Cobresal which defeat 3–1 the team in El Salvador with a hat-trick of Joel Soto. The goal for Calera was of Alejandro Risso. The following week the team was recovered from the 3–1 defeat with Cobresal, beating 2–0 to Deportes La Serena at Nicolás Chahuán Nazar, but after this victory, an important triumph was against Cobreloa in Calama with a goal of Ramón Fernández in the 17th minute. This victory meant the team's climb to the league table's first place, being there with thirteen points next to Universidad Católica. The next matchday, Católica and Calera remained as table's leaders after both teams won to Universidad de Concepción (Calera; 2–0) and Palestino (Católica; 1–2).
On 11 March, Unión La Calera had to play with giants Colo-Colo at the Estadio Monumental in the capital city of Santiago. However, the team was defeated in a 2–0 loss with goals of the Argentinian Lucas Wilchez and Chilean international José Pedro Fuenzalida. The next matchday, on 20 March, Unión La Calera defeated 3–1 as local to Audax Italiano, thereby confirming its second place behind Universidad Católica. The team began losing with a goal of Bryan Carrasco in the 20th minute, but the score of Braian Rodríguez through a penalty, gave encouragement so that later Octavio Pozo and Jorge Ampuero contribute with goals.
Emblem
The traditional shield of Unión La Calera consists of one with the colors blue and green divided diagonally, with a "U" in white and borders of the same color. Below, on a red background "La Calera" is presented. In mid-2018 this shield was registered for commercial purposes by Sabino Jadue, former head of the institution, so since 2019 the club occupies a white circular shield with a thick red border where it says “Unión La Calera”, and within the white area the abbreviation «ULC» appears in greenish bluish tones.
This change was resisted by the fans, who held demonstrations in La Calera, and started a campaign on social networks to restore the historic shield. In 2021 the traditional shield returned to the shirts, this time in conjunction with the new insignia. In January 2026, the club returned to its original emblem.
Uniform
Traditionally Unión La Calera's home kit is composed by a red shirt, white pants and white socks. Its away kit meanwhile is entirely white. During the 2007 Primera B season, Calera's home kit was symbolized by a white and red horizontal striped shirt; its pants and socks were white. This kit is similar to the one used by the team when it got its promotion to Primera División in 1984.
For the 2010 second-tier season, the titular uniform is a red shirt with vertical white bars, red pants and red socks.
Once promoted to 2018 Primera División de Chile, during that tournament, the team changed its kit colors to entirely red like the kit which occupied during the 2014–15 season.
