Olympus High School is a public high school in the Granite School District in Holladay, Utah, a suburb of Salt Lake City.

The school opened on September 1, 1953, with an original enrollment of 1028 students. In the fall of 1960, the largest entering sophomore class (the graduating class of 1963) in Utah's history (an estimated 935) enrolled. Two years later the overcrowding was reduced when the new Skyline High was completed. In April 2013, the new Olympus High School building was opened for classes adjacent to the original school. The original building was torn down after 60 years of operation.

Throughout its history, Olympus has been one of the leading academic public high schools in the state. In 1961 its orchestral and vocal music program was recognized as one of the nation's finest by the Ford Foundation, which funded a composer-in-residence for the school, an award shared with schools throughout the Granite School district.

Considered one of the greatest rivalries in the state of Utah, "the Rock" is the prized rivalry trophy between Olympus and Skyline football. It is a football-shaped piece of granite, which local lore states was taken from Mt. Olympus in 1962, prior to the first contest between the two schools. The winning school paints the Rock in their colors and displays it in their trophy case. Skyline maintains the edge, 26–23–1, but Olympus has won the Rock 7 years in a row.
