Hereford High School (Parkton, Maryland)

Hereford High School is a four-year public high school located in the rural northern Baltimore County town of Parkton, Maryland, United States, part of the Baltimore County Public Schools (BCPS). The secondary school was established in 1953.

The school's district is the Hereford Zone. The Hereford Zone covers 233 square miles (600 km²) and makes up over a third of Baltimore County by area. Just like most public schools in the district, Hereford students are transported by a busing system.

Hereford is known notably for its agriscience program. It was the only one of its kind among the county's public high schools. Hereford's base feeder school, Hereford Middle School, located in Monkton, also has a smaller agricultural program.
