This is a list of notable performances of third party and independent candidates in United States gubernatorial elections.

In the 369 gubernatorial elections since 1990, third party or independent candidates have won at least 5.0% of the vote 53 times (14%), while six candidates have won election (2%). The most recent third party or independent governor to win was Alaska's Bill Walker, a Republican turned independent, in 2014.
