Welcome to Aragon High School, Home of the Dons!  Aragon High School is a comprehensive four-year public high school located in San Mateo. We work hard to ensure that our students receive the best educational opportunities possible with a highly-qualified faculty and a staff that takes great pride in our school.

We are one of seven high schools in the San Mateo Union High School District (SMUHSD).  Since SMUHSD is an open-enrollment district, Aragon students come from the entire SMUHSD boundary area.  We serve approximately 1,730 students in the 2020-2021 school year.
