Akron () is a city in Summit County, Ohio, United States, and its county seat. It is the fifth-most populous city in Ohio, with a population of 190,469 at the 2020 census. The Akron metropolitan area, covering Summit and Portage counties, had a population of 702,219. It is located on the western edge of the Glaciated Allegheny Plateau in Northeast Ohio about 40 miles (64 km) south of downtown Cleveland.

First settled in 1810, the city was founded by Simon Perkins and Paul Williams in 1825 along the Little Cuyahoga River at the summit of the developing Ohio and Erie Canal. The name is derived from the Greek word ἄκρον (ákron), signifying a summit or high point. It was briefly renamed South Akron after Eliakim Crosby founded nearby North Akron in 1833, until both merged into an incorporated village in 1836. In the 1910s, Akron doubled in population, making it the nation's fastest-growing city.

A long history of rubber and tire manufacturing, carried on today by the Goodyear Tire and Rubber Company, gave Akron the nickname "Rubber Capital of the World". It was once known as a center of airship development. Today, its economy includes manufacturing, education, healthcare, and biomedical research; leading employers include Akron Children's Hospital, Gojo Industries, FirstEnergy, and Summa Health. Other significant institutions include the Akron Art Museum, Akron Civic Theatre, Stan Hywet Hall and Gardens, and University of Akron.

A racially diverse city, it has seen noted racial relations speeches by Sojourner Truth in 1851 (the Ain't I A Woman? speech), W. E. B. Du Bois in 1920, and President Bill Clinton in 1997.
