The Mission Viejo Marching Band & Color Guard compete in Class 3A of the Western Band Association (WBA), a nonprofit organization that promotes high school music education in California, Arizona and Nevada. In 2019, the Mission Viejo Marching Band & Color Guard won the Class 3A Championships and Grand Championships for all 1A/2A/3A classes.

Marching Band season begins with Fall Kick Off and Band Camp one week before school. We are proud to host the MVHS Field Show Tournament, or Home Comp, which begins the WBA competition season and is our major fundraiser for the year. 

Marching Band is available as a 6th period class for all students in the fall semester and counts as PE credit. The band practices after school each weekday as well as Tuesday nights on the football field. They perform pep tunes for Friday night football games and pep rallies, and compete in field show tournaments on select Saturdays from early October to the weekend before Thanksgiving.
