It is the tenth-largest city in Ukraine, and the second largest in the Donetsk Oblast with a population of 431,859 (2021 est.). The city is largely and traditionally Russophone, while ethnically the population is divided about evenly between Ukrainians and Russians. There is also a significant ethnic Greek minority in the city. Mariupol was founded on the site of a former Cossack encampment named Kalmius and granted city rights in 1778. It has been a centre for the grain trade, metallurgy, and heavy engineering, including the Illich Steel & Iron Works and Azovstal. Mariupol has played a key role in the industrialization of Ukraine.

As part of the Soviet practice of renaming cities after Communist leaders, the city was known as Zhdanov, after the Soviet functionary Andrei Zhdanov, between 1948 and 1989. Today, Mariupol remains a centre for industry, as well as higher education and business.

Following the Russian intervention in Ukraine and the capture of the city of Donetsk by pro-Russian insurgents associated with the Donetsk People's Republic in 2014, Mariupol was made the provisional administrative centre of the Donetsk Oblast. The city was seized on June 13, 2014 by Ukrainian troops, and has come under attack several times since.
