Mahanoy City (pronounced MAHA-noy) is a borough located 38 miles (61 km) southwest of Wilkes-Barre and 13 miles southwest of Hazleton, in northern Schuylkill County, Pennsylvania in the southern Coal Region. It is located entirely within but is not part of Mahanoy Township. The name "Mahanoy" is believed to be a variation of the Native American word 'Maghonioy', or "the bath salt deposits".
Mahanoy City, originally a part of Mahanoy township, was settled in 1859 and incorporated as a borough by decree of the Court of Quarter Sessions of Schuylkill County on December 16, 1863. It was served by branches of the Lehigh Valley and the Philadelphia & Reading railways.
Mahanoy City lies in a valley in the Pennsylvania Coal Region and was a major center of anthracite production; the area was embroiled in the Molly Maguires incidents. In 2010, the borough erected the Molly Maguire Historic Park, which features a Zenos Frudakis statue of a hooded miner on a gallows, about to be hanged. Sean Connery, the star of the 1970 historical drama film The Molly Maguires, served as chairman of the advisory board for the park project.
The borough's principal industries remain the mining and shipping of coal, although the demand for it has steadily declined since its peak in the late nineteenth and early twentieth centuries. In 1930 the St. Nicholas Coal Breaker was built and went into operation in 1932. A controlled explosion destroyed the breaker in March 2018.
Fire clay abounds locally. The manufacturing of shirts, bedding and foundry products is also fairly prominent.
In 1948, Mahanoy City became the first municipality in the country to have cable TV.
Mahanoy City is located at 40°48′45″N 76°8′25″W (40.812413, -76.140223), with PA 54 as a main thoroughfare and through road, serving as a main street named Centre Street.
