Sylmar is a suburban neighborhood in the San Fernando Valley and the northernmost neighborhood within the city of Los Angeles, California, United States. Historically known for its profusion of sylvan olive orchards, Sylmar can trace this back to the 18th century and the founding of the San Fernando Mission. In 1890, olive production was begun systematically. The Sylmar climate was also considered healthy, and so a sanitarium was established, the first in a series of hospitals in the neighborhood. There are fourteen public and eight private schools within Sylmar.
