The Googleplex is the corporate headquarters complex of Google and its parent company, Alphabet Inc. It is located at 1600 Amphitheatre Parkway in Mountain View, California.

The original complex, with 2 million square feet (190,000 square meters) of office space, is the company's second largest square footage assemblage of Google buildings, after Google's 111 Eighth Avenue building in New York City, which the company bought in 2010.

"Googleplex" is a portmanteau of Google and complex (meaning a complex of buildings) and a reference to googolplex, the name given to the large number 10¹⁰¹⁰⁰, or 10^googol.
