Capitol High School is a public high school named after the Louisiana State Capitol in Baton Rouge, Louisiana.
Capitol Junior - Senior High School opened in 1950 as the second public secondary school for African Americans in the city. The school's campus on was designed by Baton Rouge architect A. Hays Town. In 1959, the high school and middle school split, and the middle school remained in the original building. The Capitol Senior High School building was constructed in 1960.
The state took control of the Capitol High in 2008, citing low performance. Capitol High School became part of the RSD-Capitol Education Foundation. A plan to make it a KIPP school for the 2022-2023 school year fell through. Local control as part of the East Baton Rouge Parish School System returned during the 2023-2024 school year.
Capitol High's student body was 94.7% African American in 2024, and 71% of students are "economically disadvantaged". The school's test scores are very low.
The Leader newspaper is the school newspaper.
Capitol High athletics competes in the LHSAA. Lions are the school mascot and the school colors are red and gold.
In 2022, Johnathan Brantley was announced as head football coach.
