Cypress is a city in northwestern Orange County within Southern California. Its population was 50,151 as of the 2020 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. After World War II, however, the land became too valuable for farming or ranching, and the dairies gradually sold out to housing developers during the 1960s, so that by the 1970s no dairies remained. Many of the dairymen moved their operations to Chino, where development is once again pushing them out of the area.
In 1957, local residents voted to change the name of "Dairy City" to "Cypress". The name was taken from Cypress Elementary School (built in 1895) which took its name from the Cypress trees planted to protect the schoolhouse from the seasonal Santa Ana winds. Cypress Elementary School also provided the name for new Pacific Electric Railway station on Walker Street at Lincoln Avenue when the Santa Ana Line was completed in 1906, as "Waterville" already had been used elsewhere in the system.
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.

The city council has received a letter written by attorney Kevin Shenkman that claims existence of racially-polarized voting within the city, which combines with this election system to result in a violation of the California Voting Rights Act. The city council held forums for public input on how to respond. The council reached a decision during the March 14, 2022, council meeting's closed session to have the city attorney send a response letter. This letter disagrees with the claims and asks for more evidence.
