Mancelona (/mænˌsəˈloʊnə/ man-sə-LOW-nə) is a village in the Northern Lower Peninsula of the U.S. state of Michigan. Part of Mancelona Township, the village is located within Antrim County. Its population was 1,344 at the 2020 census.
 In 1869, Perry Andress established a homestead in the area, naming it after his daughter, Mancelona Andress. Two years later, the Township of Mancelona was established, and named after her as well. In 1872, an extension of the Grand Rapids and Indiana Railroad was extended through the area, and a station called Mancelona was established.
 In 1882, an organization by the name of "John Otis & Company" built a large charcoal furnace just south of Mancelona. The company also platted a town around the furnace, naming it "Furnaceville". Soon after this, the Grand Rapids and Indiana Railroad built a station at that town. The furnace flourished, and in 1886 a group of businessmen from Grand Rapids bought out the company, and renamed the company Antrim Iron Works and the town Antrim. A large blast furnace and iron works was built on the site, and the new company began doing business. The iron company shuttered in 1945, and was demolished in the 1980s.
