This is a list of third party and independent United States state governors, that is, governors that have not been members of the Democratic, Republican, Whig, National Republican, Democratic-Republican, or Federalist parties.
Since its founding, the United States has been a two-party system, and it is rare for independents or members of third parties to be elected to high offices such as the governorship.
The most recent-serving independent governor is Bill Walker of Alaska, who served 2014–2018.
While there have been few third parties that have gained traction at the national level, several states have been three-party systems at one point or another.
Also not included are military or appointed governors of former Confederate states after the American Civil War.
