Silliwood, a portmanteau of Silicon Valley and Hollywood, is the term given to various California companies involved with creating CD-ROM computer games based on Hollywood movies, most of which did not appeal to serious gamers in the mid-1990s. The term also referred to the advent of computer-generated imagery (CGI) in Hollywood movies.

In 1996, Steve Jobs described the term as "the space that a lot of companies were in so they can raise investment, but they never produced any products. It was sort of technology meeting Hollywood". Jobs noted that Pixar was the only successful company "where Silicon Valley and Hollywood have met".
