The 2010 Jefferson County, Missouri Executive election took place on November 2, 2010. The 2010 election was the first election for the position after voters approved the County Charter in the 2008 election, which temporarily converted the County Commission into a Board of Executives until the County Executive and a full, seven-member County Council could be elected.

In the Democratic primary, County Assessor Randy Holman defeated Chuck Banks, a member of the Board of Executives, in a landslide. Former County Treasurer Ken Waller won the Republican primary over businessman Avery Fortenberry, and faced Holman in the general election. Waller narrowly defeated Holman, winning 48 percent of the vote to Holman's 46 percent, while Libertarian Dan McCarthy won 6 percent.
