The Coastal Mountain Conference or CMC is an athletic conference for secondary schools in Mendocino, Lake, Napa and Sonoma Counties that competes in the North Coast Section of the California Interscholastic Federation. Member schools are currently organized into three leagues (North Central Leagues I, II, and III) based on school size and various other criteria found in the conference's bylaws. League assignments are automatically reevaluated in all even numbered years or at any other time by written request of a member school, provided no other members file an objection. Conference champions from all three leagues advance in each sport to post-season competition in the North Coast Section's Division V bracket, of which the winner gains admission to the Class A state championship tournament.

The CMC is a CIF Class A conference (CIF Class A guideline: mostly schools with average enrollment of 600 students or less), though several schools are classified by the CIF as Class B and elect to "play up" in the CMC due to lack of a sufficient number of other similar size schools against which to compete. Similarly Lower Lake High School holds a 2A classification from the CIF but was granted a standing exemption to compete in a Class A conference as to do otherwise would require an excessive amount of travel. Classifications range from 4A for the largest, most historically competitive schools to B for the smallest and least competitive schools.
