Calvert High School is a public high school in Prince Frederick, Maryland, United States and is part of the Calvert County Public Schools.
The campus is on Dares Beach Road and includes the main school building, a gym for basketball games, a football stadium, a baseball field, tennis courts, a soccer field, a lacrosse and field hockey field, and a large auditorium used for school concerts and plays. Additionally, it also includes the Arthur Storer Planetarium, named for the Calvert County resident and the original namesake of Halley's Comet. A vocational education center is adjacent to the main school building.
Before moving to its current campus in 1963, Calvert High School used to be along Maryland Route 2/Maryland Route 4. The building once served as a building for Calvert Middle School, a public middle school that serves as a feeder school of Calvert High. Calvert Middle School recently moved from that building and built a new school in Prince Frederick. In 1965, desegregation of the Calvert County Public Schools led to Brooks High School — the county's then all-black high school — being merged with Calvert High.
Calvert High's school mascot is the Cavalier. The sports teams compete in the Southern Maryland Athletic Conference. Calvert High's athletic rivals include the neighboring schools of Northern High School, Huntingtown High School, and Patuxent High School. In 2000, the Cavaliers captured the Maryland State Division 3A American football championship under the leadership of head coach Jerry Franks. In 2015, the Calvert High School Varsity Girls Soccer Team also added to Calvert's achievements by winning the Maryland 2A State Championship under the leadership of Dawn Lister and Damon Williams. Calvert High and Patuxent High are the only 2A schools in the county.
