The William and Flora Hewlett Foundation, commonly known as the Hewlett Foundation, is a private foundation, established by Hewlett-Packard cofounder William Redington Hewlett and his wife Flora Lamson Hewlett in 1966. The Hewlett Foundation awards grants to a variety of liberal and progressive causes, as well as conservative organizations. 
With assets of approximately $9 billion, Hewlett is one of the wealthiest grant makers in the United States. The Foundation has grantmaking programs in education, the environment, global development and population, the performing arts, and philanthropy. The Hewlett Foundation is based in Menlo Park, California.
Programs and grants
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.
The Hewlett Foundation make grants in developing countries and in the United States to provide and advocate for family planning and reproductive health services. The Hewlett Foundation has given major financial support to Planned Parenthood and the International Planned Parenthood Federation.

Data are taken from the International Aid Transparency Initiative activities publication, and is expected to cover 21% of the foundation's overall grantmaking; this does not include international grantmaking in Environment, Education, and other program areas, although those total a significant proportion of grants. The Foundation's Climate Initiative, in particular, is oriented toward international as well as U.S.-focused work. The sector names use the DAC 3 Digit Sector names.
