Our Lady of the Valley is a large Catholic church and school located in the Canoga Park section of Los Angeles, California.

Founded in 1921 when the area was sparsely populated, and most of the 620 parishioners were involved in agriculture with livestock or walnut and orange groves.

The shrine is dedicated to the Blessed Virgin Mary as Patroness of the San Fernando Valley.

At the time of its formation, the parish's boundaries covered 400 square miles (1,000 km2) from the Pacific Ocean to the south, the Ventura County line to the west, White Oak Avenue to the east, and the Santa Susana Mountains to the north.

In the years after World War II, the San Fernando Valley shifted from agriculture to residential communities, and the Catholic population also swelled.
