Brockton High School, established in 1870, is a high school located in Brockton, Massachusetts. It is a part of Brockton Public Schools. As of 2010 Brockton High School, with about 4,100 students, is one of the largest high schools in the United States and the largest high school in Massachusetts. Although widely stated by locals to be the largest high school East of the Mississippi River, it is in fact false, as this title is currently held by Brooklyn Technical High School in New York City. Brockton High School's colors are Black & Red and their mascot is the Boxers, which is a reference to the storied boxing history of the city, and also a tribute to hall-of-fame boxers Rocky Marciano and Marvin Hagler, who are both from Brockton and alumni of Brockton High School.
