Earl Warren High School is a public school located in San Antonio, Texas, United States. It is a part of the Northside Independent School District. As with all Northside ISD high schools, it is named for a former United States Supreme Court justice - in this case, former Chief Justice Earl Warren. When the school opened, the Warren family donated the robe worn by Earl Warren during the historic Brown v. Board of Education case. The robe is displayed in the school’s front office. In 2006, the Warren Academic Decathlon Team made it to state competition for the first time.
