Belgrade City Road Bypass (Serbian: Обилазница око Београда, Obilaznica oko Beograda) or simply Belgrade Bypass is a beltway, currently under construction, around the city of Belgrade, the capital city of Serbia.

It is one of Serbia's most important infrastructural projects, financed from the National Investment Plan with the financial backing of European Bank for Reconstruction and Development and European Investment Bank. Its construction is expected to alleviate Belgrade's congestion problems, and remove all transit traffic from the city center, unloading the critical Gazela and Pančevo bridges. The total length of the bypass will be 69 kilometers.

The bypass was planned by the Belgrade's general urbanistic plan, and its parts have been sporadically built for 17 years. However, the works intensified around the end of 2005. The total investment is estimated at euro 543 million, with around € 370 million remaining. Of those, 55 million come from the EBRD, 180 from the EIB, and the remainder from the National Investment Plan.

Belgrade ( /ˈbɛlɡreɪd/; Serbian: Београд; [beǒɡrad] ( listen); names in other languages) is the capital and largest city of Serbia. The city is located at the confluence of the Sava and Danube rivers, where the Pannonian Plain meets the Balkans. Its name in English translates to White city. The city proper has a population of over 1.1 million, while its metropolitan area has over 1.6 million people, making it one of the largest cities in Southeast Europe.

One of the largest prehistoric cultures of Europe, the Vinča culture, evolved around the area Belgrade in the 6th millennium BC. In antiquity, Thraco-Dacians inhabited the region, and after 279 BC Celts conquered the city, naming it Singidūn. It was conquered by the Romans during the reign of Augustus, and awarded city rights in the mid 2nd century. It was settled by the Slavs in the 520s, and changed hands several times before it became the capital of King Stephen Dragutin (1282–1316). In 1521 Belgrade was conquered by the Ottoman Empire and became the seat of a the Sanjak of Smederevo. It frequently passed from Ottoman to Habsburg rule, which saw the destruction of most of the city during the Austro-Ottoman wars. Belgrade was again named the capital of Serbia in 1841. The north of Belgrade remained a Habsburg outpost until 1918, when it was merged into the capital city. As a strategic location, the city was battled over in 115 wars and razed to the ground 44 times. Belgrade was the capital of Yugoslavia (in various forms of governments) from its creation in 1918, to its final dissolution in 2006.
