Charles Obadiah "Chuck" Baldwin (born May 3, 1952) is an American politician and founder-pastor of Crossroad Baptist Church in Pensacola, Florida. He was the presidential nominee of the Constitution Party for the 2008 U.S. presidential election and had previously been its nominee for U.S. vice president in 2004. He hosts a daily one-hour radio program, Chuck Baldwin Live, and writes a daily editorial column carried on its website, on News with Views, and on VDare.

As a Republican Party member, Baldwin was state chairman of the Florida Moral Majority in the 1980s. However, during the 2000 campaign of Republican George W. Bush for U.S. President, Baldwin left the party and began a long period of criticism of Bush. Baldwin endorsed U.S. Representative Ron Paul for the 2008 Republican nomination for president, and Paul in turn endorsed Baldwin for the presidency in the 2008 general election.

Baldwin supports ending U.S. involvement in the United Nations, reducing U.S. income taxes, and repeal of the Patriot Act. He would withdraw troops from Iraq and seek to end illegal immigration by enforcing immigration laws. He supports the gold standard, the right to keep and bear arms, homeschooling, and the proposed Sanctity of Life Act, which would define "human life" and legal personhood as beginning at conception, and prevent federal courts from hearing cases on abortion-related legislation.
