The 2010 Kansas gubernatorial election was held on November 2, 2010. Incumbent Governor Mark Parkinson, who assumed office when previous Governor Kathleen Sebelius was sworn in as the United States Secretary of Health and Human Services on April 28, 2009, declined to seek election to a full term. Senator Sam Brownback, who unsuccessfully ran for president in 2008, emerged as the Republican nominee, facing off against Democratic State Senator Tom Holland, who was unopposed for his party's nomination. Brownback defeated Holland in a landslide to become the 46th Governor of Kansas. As of 2022, this is the last gubernatorial election in Kansas where the winner received a majority of the vote.
