SG Union Sandersdorf is a football club based in Sandersdorf-Brehna, a town in the Anhalt-Bitterfeld district in Saxony-Anhalt, Germany. The club, which has around 1,000 members, plays its home matches at the Sandersdorf Sports and Leisure Center. The team's colors are green, white, and black.
The club was founded in 1911 as BC Union Sandersdorf. In 1933, SV Sandersdorf merged with Union Sandersdorf. After World War II, the club played under various names such as SG Sandersdorf and BSG Werk Hermann Fahlke Sandersdorf. In the 1948/49 season, the football department achieved its first successes as BSG Aktivist Sandersdorf when they became one of the co-founders of the new Saxony-Anhalt South state class, which was the top division in Saxony-Anhalt at the time.
Following the dissolution of the states and state leagues in East Germany, the club played in the Halle district league from 1952. In 1957, the club was forcibly merged with BSG Chemie Wolfen and appeared as BSG Chemie Wolfen II until 1959. From 1959 onwards, they played as BSG Chemie Sandersdorf and competed primarily in the district league. In 1990, following the political changes in Germany, the club transformed into the registered association SG Chemie Sandersdorf, which later changed its name to SG Union Sandersdorf in 1991.
In 1992, the football team was promoted to the district league and eventually reached the state league. In 1997, Union Sandersdorf achieved promotion to the Verbandsliga, the highest league in Saxony-Anhalt at the time. After two seasons, the club was relegated back to the regional league in 1999. They secured promotion back to the Verbandsliga and achieved their best result to date with a second-place finish in the 2010/11 season. Two years later, despite finishing second again, they were promoted to the NOFV-Oberliga Süd, the fifth-highest division in Germany, as the national champion Haldensleber SC waived their right to promotion.
The club plays its home matches at the Sandersdorf Sports and Leisure Center, which was opened in 1954 as the "Glückauf-kampfbahn Hermann Fahlke." The stadium features a covered grandstand with 280 seats and 500 standing places, a scoreboard, and a modern floodlight system. In addition to the stadium, the club has an artificial turf pitch and access to a multi-purpose sports hall and a ball sports hall.
The football section of SG Union Sandersdorf has achieved notable success, including promotions to the Verbandsliga and the NOFV-Oberliga Süd. The club also has a joint youth support association, JFV Sandersdorf/Thalheim, with SG Rot-Weiß Thalheim. The youth teams participate in various leagues organized by the Saxony-Anhalt Football Association.
