Teleoptik Zemun

FK Teleoptik (Serbian Cyrillic: ФК Телеоптик) is a football club based in Zemun, Belgrade, Serbia. They compete in the Serbian First League, the second tier of the national league system. The club was founded by the manufacturing company of the same name in 1952. They played in the local leagues of Belgrade within the Yugoslav football league system, but without notable achievements. In the early 1990s, when the country started breaking apart, the club agreed to an affiliate partnership with FK Partizan. One of the most significant aspects of this cooperation was the construction of the SC Partizan-Teleoptik, which was officially opened in May 1998. In the NATO bombing-suspended 1998–99 season, the club finished second in the Serbian League Belgrade and gained promotion to the Second League of FR Yugoslavia. After easily securing league status in their debut appearance, they made an even better result in the 2000–01 season, earning a fifth-place finish. However, the club failed to avoid relegation in 2002, when the competition changed its format. In 2009, having spent seven consecutive seasons in the Serbian League Belgrade, the club reached the Serbian First League after finishing in second place and defeating Serbian League East runners-up Timok in the promotion play-offs. They remained in the second tier for five seasons until relegation in 2014. After winning the Serbian League Belgrade in 2017, the club returned to the Serbian First League, but again suffered relegation in 2019.
