Topčider (Serbian Cyrillic: Топчидер, Serbo-Croatian pronunciation: [tɔ̝̌pt͡ʃide̞r]) is a forest park and an urban neighborhood of Belgrade, the capital of Serbia. It is divided between in the municipalities of Čukarica, Rakovica and Savski Venac. Being close to downtown, it is one of the major locations for relaxation, picnics and fresh air for the citizens of Belgrade.
Geographically, Topčider covers a much larger area than what people generally refer to as Topčider today. The eastern slopes of Topčidersko Brdo ("Topčider Hill") begin already at the Mostarska Petlja and the highway. The neighborhood of Senjak is located on the western, and Dedinje on the right side. This is where the street of Topčiderski Venac and the roundabout of Topčiderska zvezda ("Topčider star") are located. The southern slopes of the hill extends into the valley of the Topčiderska reka, a tributary to the Sava river, which has been channeled in this section. This is the area identified with the term Topčider. Topčider Park begins five kilometers south of downtown Belgrade and extends west, east and south into the old Topčider woods which itself extend west into the park-wood of Košutnjak. In the upper parts, Košutnjak and Topčider forests grow together, while in the lower parts they are divided by the Topčiderska reka and a railway passing through the river valley (both Košutnjak and Topčider have their own, separate train stations). In the extreme north-west Topčider extends into the neighborhood of Careva Ćuprija and in the south-east into Lisičji Potok. It also borders the neighborhood of Kanarevo Brdo in this section.
