Dorchester High School predated the annexation of Dorchester to Boston. At its founding, it was an all-male school, first opened on December 10, 1852. In 1870 Dorchester was annexed to Boston and its schools became managed by the City of Boston. A replacement facility opened in Codman Square on Talbot Avenue 1901. The current Dorchester facility opened in 1925 on Peacevale Road to males, while the Talbot Avenue building was for females. In 1953 Dorchester High School consolidated as a coeducational school.
