Extremadura Unión Deportiva was a Spanish football team based in Almendralejo, in the autonomous community of Extremadura. Founded in 2007, it last played in Primera División RFEF – Group 1, holding home games at Estadio Francisco de la Hera.
Extremadura Unión Deportiva was founded in 2007, as the existing CF Extremadura club was experiencing serious financial problems, which would lead to its folding three years later.
In only three seasons, the club reached the third division of Spanish football, having won in the 2010 playoffs against Atlético Mancha Real in June 2010. However, it finished 19th and last (due to AD Cerro de Reyes Badajoz Atlético retiring from competition) in its first campaign, being immediately relegated back.
Extremadura won their fourth-tier group in 2013, qualifying for the Copa del Rey for the first time. There, they lost 2–1 at home to Albacete Balompié in the first round.
In 2016, Extremadura were promoted again to Segunda División B with a 2–0 aggregate play-off win over UB Conquense. In 2018 the club was promoted for the first time to Segunda División after defeating FC Cartagena 1–0 on aggregate in the last round of the play-offs.
One of the stars of Extremadura's promotion was Enric Gallego, who arrived halfway through the season from UE Cornellà, and scored 15 goals in 19 games in his first professional campaign at the age of 32 before leaving for La Liga club SD Huesca in January 2019 for €2 million. After falling into the relegation zone around that point in the season, the club fired Rodri and hired Manuel Mosquera who guided them to safety; the end of the campaign was also marked by the death of veteran winger José Antonio Reyes in a car accident.
In July 2020, Extremadura was relegated back to the third tier after losing by a single goal away to Cádiz CF, amidst problems between the club president and shareholders. The club faced financial difficulties during the most of the 2021–22 season, with several players opting to leave during the winter transfer window.
Extremadura changed ownership in January 2022, but as the financial problems were unsolved, the players began a strike in February. On 28 February, after two consecutive no-shows in the competition, the club was expelled from the division; RFEF confirmed the decision on 2 March, with the club being immediately relegated and being unavailable for promotion in the ensuing campaign.
In May 2022, as the club was already in a liquidation process, a new club named CD Extremadura 1924 was founded in the city, with the goal of obtaining Extremadura UD's place in the Segunda División RFEF.
