Iron Mountain High School is a public high school located in the city of Iron Mountain, Michigan, United States.

The Iron Mountain Public School District also includes North Elementary, East Elementary, and Central Middle School. As of 2020, both the Central Middle School and East Elementary buildings are not in use. The North Elementary building holds grades EK–4, and the Iron Mountain High School building holds grades 5–12.

The first school in the Iron Mountain area opened in 1881 on the corner of Brown and Iron Mountain Street, where classes were held from 1881 to 1893. Another one-room school was built sometime between 1882 and 1884 on Fifth Street in Iron Mountain. In 1884, the Central School building was built at 300 West B Street, where the current high school building stands. This building had two stories with eight rooms and housed all grades, and whose first graduating class of three students graduated in 1889. Subsequent public schools built in Iron Mountain before Iron Mountain High School were Chapin School in 1889, Ludington School in 1891, Hulst School in 1892, Lincoln School in 1896, Farragut School in 1899, and Washington School in 1900.

Once it was decided that a new building needed to be constructed to accommodate the expanding population of the Iron Mountain area, the Central School building was relocated 2 blocks north. The Iron Mountain High School building was proposed in 1911 by architects Charlton & Kuenzli, and was built between 1911 and 1912. The building was opened in 1912 and classes began that same year. In 1914, Iron Mountain High School was one of eight different school buildings in the Iron Mountain area. From then on schools in Iron Mountain would continue to close their doors.

In 1937, classes stopped being held at the Central School and the building was razed to make way for a new Iron Mountain Junior High School. Later renamed Central Middle School, this building would house classes for junior high school students in the Iron Mountain Public School District. This building, completed in 1938, was a project under the Public Works Administration. The Public Works Administration supplied an $89,860 grant for the project, whose total cost was $201,387.

An addition was built alongside the Central Middle School building in 1994, which included five classrooms, a gymnasium, a cafeteria, and locker rooms. Eventually, the Central Middle School building held classes for K-8 students, but in 2014, plans to sell or demolish the Central Middle School building were discussed as the classes once taught here were transferred to the Iron Mountain High School building. Beginning in 2015, the Iron Mountain High School building holds all grade 5-12 students in the Iron Mountain Public School District, while the North Elementary building, located on the north side of Iron Mountain, holds grades EK-4.
