Muhar (Serbian Cyrillic: ?????) is an urban neighborhood of Belgrade, the capital of Serbia. It is located in the Belgrade municipality of Zemun.
Muhar is centered around the Branko Radi?evi? Square. Geographically, it is a small, narrow valley between the hills (and neighborhoods) of Gardoš to the north and ?ukovac to the south, some of the oldest sections of Zemun. It forms a natural connection between the much larger Zemun neighborhoods of Donji Grad further south and Gornji Grad to the north.
Muhar was named after Ivan Muhar (1867–1966), one of the most famous merchants in pre-World War II Zemun. Starting as an apprentice, he later opened his own store in the square and, as the business grew, later built a mansion (ku?a Ivana Muhara) which is one of Zemun's main landmarks. Subsequently, the entire area around the square became known as Muhar. Today, the square officially bears the name of Branko Radi?evi?, a 19th-century Serbian Romanticist poet.
Muhar is one of Zemun's major crossroads. It marks the ending senction of Glavna street, Zemun's main street. Through the Karamatina and Njegoševa streets on the east it is connected to the Zemunski Kej, while on the north-west, through the streets of Cara Dušana and Dobanova?ka, it extends into the neighborhood of Gornji Grad. However, Muhar is too narrow for such traffic capacity and is a regular place of traffic congestion, especially in the rush hours.
Muhar is also the location of the Madlenianum Opera and Theatre. The entire area of Gardoš-Muhar-?ukovac is known for its vast net of lagums, underground corridors. So far, 73 long corridors have been discovered, with lots of smaller ones. The longest of them is Template:Convert long.
