The 2019 Snohomish County Executive election took place on November 5, 2019, to elect the county executive of Snohomish County, Washington. Incumbent Democratic County Executive Dave Somers ran for re-election to a second term.
However, no candidate announced a campaign against Somers by the candidate filing deadline, and he was re-elected unopposed. Though several elected Republicans in the county were interested in running for County Executive in the future, the chairwoman of the county Republican Party said that "[t]here wasn't anybody who wanted to run" against Somers in his bid for a second term.
Somers ultimately received 93 percent of the vote in the primary election, and 94 percent in the general election.
