The Zemun Gymnasium () is the most prominent gymnasium in Belgrade, Serbia. It is located in Belgrade’s Zemun municipality. Founded in 1858, it's Belgrade second oldest, after the First Belgrade Gymnasium (founded in 1839), and Serbia's sixth oldest gymnasium, after those in Sremski Karlovci (founded in 1791), Novi Sad (founded in 1810), Kragujevac (founded in 1833) and Šabac (founded in 1837). By the number of students, it is the largest gymnasium in Serbia today. History The gymnasium was founded on 23 September 1858 on the orders of the Austrian military command in Zemun as a two-year lower realgymnasium. It initially had only one grade and just 21 students. Zemun was then a part of the Austrian Empire that was to become Austria-Hungary, and the language of instruction was German. By 1872 the gymnasium had four grades. In 1883 it was decided that Serbian should be the language of instruction, and a year later, on the orders of the Government, girls were restricted to the first grade, so it was solely for boys by 1887. Due to World War I events, the school experienced a multitude of problems, and did not start functioning normally again until 1925.

First cinema in Zemun was open in the school building in 1926. Today's gymnasium exists since 1958, after a merger with two smaller schools (for boys and for girls) created in 1946 after the liberation of Serbia & Yugoslavia from the Nazis by the Communist Partisans and the Red Army. For a while, a Commerce school was located in the building, while in the 1970s the gymnasium was organized as an "educational center". In 2008, the Zemun Gymnasium celebrated its 150th anniversary. In the 2017/18 school year 320 first graders were admitted in total of 11 classes. They are divided in three sections: sociolinguistic, natural sciences-mathematics and physics. Additional 12th grade, for informatics, is planned for 2018/19.
