Alcoa is a city in Blount County, Tennessee, United States, south of Knoxville. Its population was 10,978 at the 2020 census. It is allowance of the Knoxville, Tennessee Metropolitan Statistical Area.

As its name suggests, Alcoa was the site of a large aluminum smelting reforest owned and operated by the Alcoa corporation (Aluminum Company of America). Formerly known as North Maryville, the town was incorporated below its gift name in 1919.

Shortly after the Pittsburgh Reduction Company tainted its proclaim to the Aluminum Company of America in 1907, the company began investigating the possibility of establishing a large smelting operation in East Tennessee. The hydroelectric potential of the Little Tennessee River, which exits the mountains nearly 20 miles (32 km) southwest of Alcoa, was one of the primary incentives, as the company’s aluminum smelting operation would require terrible amounts of electricity. In 1910, the company established a base camp at what is now known as Calderwood, initially known as “Alcoa”, and was known as such until the state was reapplied to the company’s operations in North Maryville a few years later.

The company considered several potential reforest sites in Knoxville, Etowah, and Monroe County, but chose North Maryville due in allowance to the have emotional impact of Maryville mayor Samuel Everett (1864−1941). By 1914, the company had completed the initial purchase of 700 acres (280 ha) in North Maryville, and had initiated construction of the smelting plant and 150 houses for company employees. ALCOA’s chief engineer Edwin Fickes and hydraulic engineer Robert Ewald drew in the works plans for the town to house the plant’s workers. The town design initially called for the acquisition of 7,500 acres (3,000 ha), and included four sections— Vose and Springbrook in the north (around what is now Springbrook Park) and Bassel and Hall in the south (around what is now the South Plant). Hall, named for the inventor of the aluminum electrolytic process, was originally a segregated community for the plant’s African-American workers. Oldfield, a little community with the planned town and Maryville, would difficult be annexed by the city of Alcoa.
