The Marmonte League is a high-school sports league primarily made up of schools from Ventura County and the far western edge of Los Angeles County, California. The Marmonte League is part of the CIF Southern Section.
Following the 2014 re-leaguing, the league (for most varsity sports) consists of:
These schools (along with Oak Park HS and Adolfo Camarillo HS) went on to form the Coastal Canyon League:
Previously these schools had been part of the Marmonte League:
before they joined the Pacific View League on its formation.
Plans to revamp the entire northern area of the CIF Southern Section, which included the Marmonte League, were in place for 2014. Those plans were quashed when Oaks Christian and St. Bonaventure challenged the plan that would have them move out of the area leagues into a parochial league. In March 2013, the two schools each won their appeal, forcing them to remain in local leagues. In April 2014, a new plan was approved, which will effectively add Adolfo Camarillo High School and Oak Park High School to the league, but will split the Marmonte League into two leagues, one of which will retain the Marmonte League name (though it had not been announced which one). The above list is the result of the change. The newly created league became the Coastal Canyon League, with St. Bonaventure moving to the new Tri-County Athletic Association.
The following are the sports in which the schools of the Marmonte League participate. The division(s) in which the schools of the league compete is listed for each sport.
In 2011 CIF and the Marmonte League decided to deny a Derrick "Deejay" Brown a transfer request thereby preventing him from playing basketball after Thousand Oaks High basketball coach Richard Endres decided to become Brown's guardian. Brown was the victim of domestic violence in 2009, when his stepfather attempted to kill both Brown and his mother by stabbing them in the face.
At the hearing to determine Brown's eligibility, Marmonte league principals barred Endres from speaking or arguing on behalf of Brown. "They don't like it that he's living with me", said Endres, regarding Marmonte principals. The decision to ban the teen from playing is widely disagreed upon by the community.
