Linfield Christian School (LCS) is a private, co-educational, college-preparatory K-12 Christian school located on a 100-acre campus in Temecula, California, a city that is located between San Diego and Los Angeles.

Rapid increases in enrollment necessitated several relocations of the campus within Los Angeles.

Don Odell was president at the time of the relocation and Dr. Robert Mounce was the first headmaster.

Linfield is also a member of the National Association for College Admission Counseling and subscribes to the Statement of Principles and Good Practice.

Linfield Christian High School competes with teams in the California Interscholastic Federation.
