High Quality Content by WIKIPEDIA articles! Cupertino is a suburban city in Santa Clara County, California, U.S., directly west of San Jose on the western edge of the Santa Clara Valley with portions extending into the foothills of the Santa Cruz Mountains. The population was 50,546 at the time of the 2000 census. It is the home of the worldwide headquarters of Apple, Inc. Cupertino was named after Arroyo San José de Cupertino (now Stevens Creek). The creek had been named by Spanish explorer Juan Bautista de Anza's cartographer, who named it after Saint Joseph of Cupertino. Saint Joseph (born Giuseppe Maria Desa, and later known as Giuseppe da Copertino) was named after the town of Copertino in the Apulia region of Italy. The name Cupertino first became widely used when John T. Doyle, a San Francisco lawyer and historian, named his winery on McClellan Road "Cupertino". After the turn of the twentieth century, Cupertino displaced the former name for the region, which was "West Side".
