This is a list of persons who have served as members of U.S. state legislatures while enrolled in third parties. For purposes of this list, a third party is defined as any party other than the Democratic Party or the Republican Party. This list spans the period from 1856 to the present. The time period listed beside each elected official's name is the time period when that elected official has served as a state legislator while enrolled as a member of a third party. State legislators who are independent (in other words, not enrolled in a political party) are not included in this list.
