泽蒙（塞尔维亚语：Земун，德语：Semlin，塞姆林）是组成塞尔维亚首都贝尔格莱德的17个自治市之一，位于萨瓦河和多瑙河汇流处。

Zemun (Serbian Cyrillic:Земун, pronounced [zěmuːn]) is a historical town and one of the 17 municipalities which constitute the City of Belgrade, the capital of Serbia. Before 1934, it was a town separate from Belgrade. The development of New Belgrade in the late 20th century, joined them together in a continuous urban area.
