Redan High School is a public secondary school of the DeKalb County School District located in Redan, Georgia. Redan was established in 1976 by the DeKalb County School District. The school's mascot is the Raider. Both Redan High School and its "twin," Stone Mountain High School, were built without any main windows on their exteriors (except for in the main common area).
