The Libertarian National Convention is held every two years by the Libertarian Party (United States) to choose members of the Libertarian National Committee (LNC), and to conduct other party business. In presidential election years, the convention delegates enact a platform and nominate the Libertarian presidential and vice-presidential candidates who then face the nominees of other parties in the November general election.

While most delegates to the Republican National Convention and the Democratic National Convention are tied to particular candidates, delegates to the Libertarian National Convention are free to choose, as was previously the case for the larger parties. Accordingly, Libertarian National Conventions place less emphasis on festivities and spinning the press, though some of each may be found. The complete convention is televised by C-SPAN with additional broadcast television coverage of the presidential nominating process. None of the above is always an option on all ballots.

The first Libertarian National Convention was held in 1972 in Denver, Colorado. John Hospers and Theodora Nathan were nominated presidential and vice presidential candidates, respectively. The party received the first electoral vote won by a woman, cast by Roger MacBride.

The 1973 Convention was held in Strongsville, Ohio, from June 8 to 10. Over 175 were in attendance.

The 1974 convention adopted the Dallas Accord which sought to accommodate supporters of both anarcho-capitalism and minarchism.

The 1975 convention was held at the Statler-Hilton hotel in New York City. Roger MacBride was nominated for president. After initially selecting None of the Above, the convention's delegates nominated David Bergland for vice president.

The 1976 convention was held in Washington, D.C., from September 23 to 26, 1976.

The 1977 convention was held at the Palace Hotel in San Francisco, California. (More details soon)
