Campbell is a city in Santa Clara County, California, and part of Silicon Valley, in the San Francisco Bay Area. As of the 2010 U.S. Census, Campbell's population is 39,349. Although not a major high-tech city like many of its neighbors, Campbell is the original home of eBay and of its creator, Pierre Omidyar.

Campbell is home to the Pruneyard Shopping Center, a sprawling open-air retail complex which was involved in a famous U.S. Supreme Court case that established the extent of the right to free speech in California. Today the Pruneyard Shopping Center is home to the South Bay offices of the Federal Bureau of Investigation.

Most residences are single-family homes, although there are some areas with condominiums, duplexes, and apartments. Single-family homes typically have one or two bathrooms and three or four bedrooms and are between 1,000 square feet and 1,600 square feet on lots typically measuring about 6,000 square feet. 

The vast majority were built in the 1950s through 1970s. There are pockets of older homes, mostly near downtown, often in demand for their architectural styles.[citation needed] There are also pockets of newer, much larger homes about 3,500 square feet, mostly built in the 1990s on subdivided lots previously occupied by homes dating from the first half of the 20th century. Most of Campbell's apartments are located in northern Campbell on Hamilton and Campbell Avenues.

As of April 2016, the median price of single-family homes and condos was $1,026,700 or $677 per square foot according to the Zillow.

Like many other cities in the Santa Clara Valley, Campbell was originally orchard land that was later developed into housing tracts.
