Welcome to Mission Hills High School! 

Mission Hills High School opened in August, 2004 and is nestled amongst the hills in the beautiful and fast-growing City of San Marcos, approximately thirty miles north of downtown San Diego.

Situated on forty-four acres of former dairy land, Mission Hills High School boasts commanding views of the surrounding community. Our spectacular campus enjoys abundant sunshine and fresh sea breezes, a wide-open plaza, four interior courtyard spaces and an outdoor amphitheater. In addition, our library, theater, gymnasium, and stadium are truly breathtaking. Specialized facilities for the sciences, arts and career-oriented programs, complement the design of basic classroom learning spaces, all focused on high achievement and a welcoming home for our 2800 students. Mission Hills offers a four-year comprehensive high school program with courses ranging from College Prep, Career Technical Education (CTE) Honors (H) and Advanced Placement (AP) classes; which may result in college credit for work done in high school. In addition to a strong academic program, MHHS provides many opportunities for students to become involved in student government, athletics, music, drama, community service, and other extracurricular activities that help bring a challenging and rewarding experience to our students and staff.

We pride ourselves on our commitment to high standards and a nurturing environment for all members of our greater community.
