Unión Deportiva Almería, S.A.D. (Spanish pronunciation: [uˈnjon depoɾˈtiβ(a) almeˈɾi.a]) is a Spanish professional football club based in Almería, in the autonomous community of Andalusia. Founded on 26 July 1989 and known as Almería Club de Fútbol until 2001, when it was renamed Unión Deportiva Almería. The club currently plays in the Spanish Primera División after winning the Segunda División title in 2022, and plays their home games at the 15,274-seat capacity Power Horse Stadium.
The first football club in Almería was founded in 1909: el Almería Foot-Ball Club. Since then, several Almería football clubs appeared and disappeared. One of them was AD Almería, a team that played in La Liga between 1979–81, but disappeared in 1982, and was arguably UD Almería's predecessor.
In 1989, a club named Almería Club de Fútbol was born, but in 2001 was renamed Unión Deportiva Almería. On 19 January 2001 the mayor of Almería Santiago Martínez Cabrejas announced in the city council that the new club UD Almería had been formed after the merger of two city teams - Polideportivo Almería and Almería CF. But UD Almería was not official until June 28, 2001, when Almería CF approved at the General Meeting of Shareholders the renaming. After playing one season in the second division, it was relegated to the third and the fourth divisions.
