Chelyabinsk (Russian: Челя́бинск, tr. Chelyábinsk, IPA: [tɕɪˈlʲæbʲɪnsk] (listen)) is a city and the administrative center of Chelyabinsk Oblast, Russia. It is the seventh-largest city in Russia by population, with 1,130,132 inhabitants as of the 2010 Census, and the second largest city in the Ural Federal District, after Yekaterinburg. Located in the northeast of the oblast, 210 kilometers (130 mi) south of Yekaterinburg, the city is just to the east of the Ural Mountains. It sits on the Miass River, part of the border between Europe and Asia.

The area of Chelyabinsk contained the ancient settlement of Arkaim, which belonged to the Sintashta culture. In 1736, a fortress by the name of Chelyaba was founded on the site of a Bashkir village. Chelyabinsk was granted town status by 1787. Chelyabinsk began to grow rapidly by the early 20th century as a result of the construction of railway links to European Russia and Siberia, including the Trans-Siberian Railway. Its population reached 70,000 by 1917. Under the Soviet Union, Chelyabinsk became a major industrial centre during the 1930s. The Chelyabinsk Tractor Plant was built in 1933. During World War II, the city was a major contributor to the manufacture of tanks and ammunition.

Chelyabinsk remains an important industrial centre, especially heavy industries such as metallurgy and military production. It is home to several educational institutions, mainly South Ural State University and Chelyabinsk State University. In 2013, the Chelyabinsk meteor exploded over the Ural Mountains, with fragments falling into and near the city. The blast of the explosion caused many hundreds of injuries, some of them serious, mostly caused by glass fragments from shattered windows. The Chelyabinsk Regional Museum contains fragments of the meteorite.
