The Hewlett Foundation is based in Menlo Park, California.

In 2001, the foundation gave $400 million to Stanford University for humanities, sciences, and undergraduate education. At the time, the gift was the largest on record to a university. In 2007, the Hewlett Foundation made a $113 million donation to the University of California at Berkeley to create 100 new endowed professorships and provide financial help for graduate students.
In May 2010, the Hewlett Foundation announced its strategy of "Deeper Learning", which is a set of student educational outcomes including acquisition of robust core academic content, higher-order thinking skills, and learning dispositions.
In 2008, the foundation awarded the Climate Works Foundation approximately $460,800,000. Hewlett funded restoration of the Bay Area Salt Ponds and conservation of the Great Bear Rainforest in Canada.
Hewlett's Environment Program makes grants to support conservation in the North American West, reduce global warming and conventional pollution resulting from the use of fossil fuels, and promote environmental protection efforts in California. The Hewlett Foundation opposes coal and natural gas development. . However, the Hewlett Foundation is a donor to the Breakthrough Institute, which promotes the use of fracked natural gas.
