The 2020 Libertarian Party presidential primaries and caucuses were a series of electoral contests to indicate non-binding preferences for the Libertarian Party's presidential candidate in the 2020 United States presidential election. These differ from the Republican or Democratic presidential primaries and caucuses in that they do not appoint delegates to represent a candidate at the party's convention to select the party's presidential nominee.
