The City of Cypress is located in North Western Orange County.
Cypress is a city in northern Orange County within Southern California. Its population was 47,802 at the 2010 census. Cypress originally was nicknamed “Waterville” due to the preponderance of artesian wells in the area, but was incorporated under the name Dairy City in 1956 by local dairy farmers as a means of staving off developers and to preserve their dairies, much like the then-neighboring cities of Dairy Valley in Cerritos and Dairyland in La Palma. In 1981 the City of Cypress inaugurated an annual birthday celebration for the City. The event, the Cypress Community Festival, currently may be the largest single-day event of its kind in Orange County, California. The Cypress Community Festival is held annually on the 4th Saturday in July at Oak Knoll Park, located adjacent to the Cypress Community Center at 5700 Orange Avenue, between Valley View Street and Walker Avenue.
