La Cañada Flintridge is a city in Los Angeles County, California, with a population of 20,246 in 2010. It is located in the Crescenta Valley and far western end of the San Gabriel Valley, to the northwest of Pasadena. It is the home of NASA’s Jet Propulsion Laboratory.
During the Spanish and Mexican eras, the area was known as Rancho La Cañada. Before the city’s incorporation in 1976, it consisted of two distinct communities, La Cañada and Flintridge. La Cañada comes from the Spanish word cañada (pronounced «canyada»), meaning canyon, gorge, or ravine; Flintridge was named after its developer, United States Senator Frank P. Flint.
