Ronald Ernest Paul, M.D. (born August 20, 1935 in Pittsburgh, Pennsylvania) is an American physician and Republican Congressman for the state of Texas. Paul is a member of the Liberty Caucus of Republican congressmen which aims to limit the size and scope of the federal government, and serves on the House Foreign Affairs Committee, the Joint Economic Committee, and the Committee on Financial Services, where he has been an outspoken critic of American foreign and monetary policy.

Paul has run for President of the United States twice, first in 1988 as the nominee of the Libertarian Party and again in 2008 as a Republican. Despite the lack of traditional organization or media attention, his 2008 Republican primary campaign attracted an enthusiastic following by making extensive use of the Internet and social networking.

He is the founder of the advocacy group Campaign for Liberty and his ideas have been expressed in numerous published articles and books, including The Revolution: A Manifesto (2008).
