The Snohomish County Executive is the head of the executive branch of Snohomish County, Washington.

The position has four-year terms (with a term limit of three consecutive terms) and is a partisan office.

[1] County voters approved the adoption of a home-rule charter for Snohomish County on November 6, 1979, creating the position of a county executive and a five-member county council.

Prior to the adoption, the county government was led by three commissioners elected at-large.

[2][3] The new position took effect on May 1, 1980, with Willis Tucker elected as the first executive.
