The 2004 Libertarian Party presidential primaries allowed voters to indicate non-binding preferences for the Libertarian Party's presidential candidate. These differed from the Republican or Democratic presidential primaries and caucuses in that they did not appoint delegates to represent a candidate at the party's convention to select the party's nominee for the United States presidential election. The party's nominee for the 2004 presidential election was chosen directly by registered delegates at the 2004 Libertarian National Convention, which ran from May 28 to 31, 2008. The delegates nominated Michael Badnarik for president and Richard Campagna for vice president.
