Campbell ( /ˈkæmbəl/) is a city in Santa Clara County, California, a suburb of San Jose, 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 neighbours, Campbell is the original home of eBay and of its creator, Pierre Omidyar.
Campbell is home to the Pruneyard Shopping Centre, 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. The larger of the associated Pruneyard Towers, built in 1970, was for many years the tallest building between San Francisco and Los Angeles. Today the Pruneyard Shopping Centre is home to Democrat Mike Honda and the South Bay offices of the FBI.
Campbell is bordered on the east and north by San Jose and on the south by Los Gatos. A narrow strip of San Jose separates Campbell on the west from Saratoga.
According to the United States Census Bureau, the city has a total area of 5.9 square miles (15 km2). 5.8 square miles (15 km2) of it is land and 0.1 square miles (0.26 km2) of it is water.
Of the total area, 1.49% is water, consisting of percolation ponds in Los Gatos Creek Park and in other locations; San Tomas Aquino Creek, which flows north on the west side of the city, is completely enclosed with fences and runs through concrete culverts; and Los Gatos Creek, which flows north-north-east on the east side of the city and has paths along both banks for hikers and joggers (locally called the "Par Course").
State Route 17 runs roughly parallel to Los Gatos Creek on its eastern side; State Route 85 runs roughly east-west through Los Gatos just south of Campbell and cuts through the southwest corner of the city.
