Girls' High School was a high school that was located in Roxbury, Boston. It was founded in 1852 by a group including Dr. LeBaron Russell. It was initially located above a public library in the former Adams schoolhouse on Mason Street. The school became coeducational in the latter half of the 20th century. By spring 1974, the school housed 500 female students and 200 male students. That spring, the Boston School Committee voted to change the school's name to Roxbury High School. This name was the most popular among petitioning students. Roxbury High closed in 1981
