It lies within a large urban area and serves as the administrative center of Kryvyi Rih Raion. It hosts the administration of Kryvyi Rih rural hromada, one of the hromadas of Ukraine.

Located at the confluence of the Saksahan and Inhulets rivers, Kryvyi Rih has been a major settlement for most of its history. It was founded as a postal station in 1775 by the Cossacks. Developed as a military settlement until 1860, it formed part of Kherson Governorate. It was incorporated during the 20th century with areas of Yekaterinoslav. The settlement began to expand "at an astonishing rate" at the beginning of the 1880s. Kryvyi Rih's urbanization was unplanned and stimulated by mining exploitation. French and English investment contributed to a boom in metallurgy, iron mining, and investigation of rich deposits of iron ore. The Catherinine Railway was built in 1884 to transport iron ore to the Donbas. This catalyzed the growth of Kryvyi Rih into a major industrial town; it gained city status in 1919.

Nationalization and investment spurred by Soviet authorities led to extensive growth. In 1934 Kryvorizhstal was built, the first of more than 500 factories. Kryvyi Rih National University was founded here. Financially, the city's postwar growth after the Nazi occupation increased after 1965 due to economic reforms. Also, investment spurred by Ukrainian Independence, institution of a market economy led to extensive regeneration, particularly in the city centre.

As of 2016 Kryvyi Rih is arguably the main steel-industry city of Eastern Europe. It is a large, globally important centre of the iron-ore mining and metallurgy region, known as the Kryvbas.
