The 1808 United States presidential election was the sixth quadrennial presidential election, held from Friday, November 4, to Wednesday, December 7, 1808. The Democratic-Republican candidate James Madison defeated Federalist candidate Charles Cotesworth Pinckney decisively.

The Republican Party, retroactively called the Democratic-Republican Party, and also referred to as the Jeffersonian Republican Party among other names, was an American political party founded by Thomas Jefferson and James Madison in the early 1790s that championed liberalism, republicanism, individual liberty, equal rights, decentralization, free markets, free trade, agrarianism, and sympathy with the French Revolution. The party became increasingly dominant after the 1800 elections as the opposing Federalist Party collapsed.
