Marion High School, Educational building in Marion, South Carolina, United States.

Marion High School is a one-story brick school building in Marion, South Carolina, built in 1923–1924 in the Classical Revival style. Its main façade has baroque massing with projecting central and end pavilions. When it opened it held a gymnasium, physics and chemistry laboratory, domestic science rooms for sewing and cooking, an agriculture laboratory and a commercial department.

Marion High School was built in 1923–1924 as a one-story Classical Revival brick school. It served as a high school until 1975, then housed Marion Elementary School until 1994, when it became the Marion County School District headquarters. It was listed on the National Register of Historic Places in 2001.

The building's name comes from its years as Marion's high school, which moved out in 1975; Marion Elementary School then occupied it until 1994. Since 1994 it has housed the headquarters of the Marion County School District, so the former classrooms and laboratories now serve as district offices.

The building is not a museum: since 1994 it has housed the Marion County School District headquarters, so visits mean contacting the district office rather than walking in. It stands on a one-story brick footprint, with the entrance under the projecting central pavilion of the main façade.

The 1923–24 building was fitted out with rooms for physics and chemistry, domestic science with sewing and cooking, agriculture and commerce, plus a gymnasium — a range of subjects unusual for a small South Carolina high school of the period.
