A conservative think tank is an organization that advocates conservative policies and ideas. The term conservative think tank is often interpreted as a politically biased group which focuses on promoting conservative views. However, there are various other synonyms that can be used to describe a conservative think tank such as policy institute, research organization, public policy center, and advocacy group. These institutions provide research, analysis, and solutions to complex policy issues to shape the political agenda. Some prominent conservative think tanks in the United States are the Heritage Foundation, American Enterprise Institute, and Cato Institute. Such organizations advocate for limited government, free markets, and traditional values.
