Diplomatska Kolonija (Serbian: Дипломатска Колонија) is an urban neighborhood of Belgrade, the capital of Serbia. It is located in Belgrade's municipality of Savski Venac.
Diplomatska kolonija is a small sub-neighborhood of Dedinje, located in its eastern section, right behind the Dragiša Mišović hospital and south of the Rajko Mitić Stadium, football stadium of the FK Crvena Zvezda. The neighborhood of Stadion is just north of it. It is generally centered on the street of the same name Diplomatska kolonija (Serbian for "diplomatic colony").
