Located in the northern portion of the San Diego city limits, Mira Mesa is located in an area once situated by Native American tribes. Due to much of the land being considered wasteland, it was not put to much use for years until in the early 1960s. Developers saw its potential to relieve the housing shortage San Diego was facing.
In 1974, a school bond issue was passed to help build the schools that the now full-fledged town of Mira Mesa sorely needed. On September 13, 1976, Mira Mesa Jr./Sr. High School was opened and now serves grades 9-12, fed by the local Challenger and Wangenheim Middle Schools.
Since 1998, Mira Mesa High School has seen an increase in diversity among its students. As of the 2014-15 school year, the student body was composed at around 28% Filipino, 22% Hispanic, and 14% White.
Mira Mesa High School’s Athletics programs include: Football, basketball, field hockey, waterpolo, swimming, baseball, soccer, tennis, cross country, cheerleading, volleyball, badminton, softball, wrestling, lacrosse, track and field etc.
The Mira Mesa Wrestling team won its first ever CIF Championship (Division 1) in 2014. The wrestling team has also won Six consecutive Eastern League Titles (2012-2017) and six consecutive San Diego City Conference Titles (2012-2017).
