The 2022 Santa Clara County Board of Supervisors election was held on November 8, 2022, to elect two of the five seats on the Board of Supervisors of Santa Clara County, California. District 1 was an open seat due to the terming out of Supervisor Mike Wasserman.[1] The race was highly competitive and the first since the 2020 United States redistricting cycle which changed the boundaries of the district.[2] Since District 4 was uncontested, incumbent Supervisor Susan Ellenberg did not appear on the November 8th ballot.
Santa Clara County is the 18th largest county in the United States and the 6th largest in the state of California. All local elections in California are officially nonpartisan and use a top-two primary system; if no candidate receives a majority of the June 7, 2022 vote, a runoff was held between the top two candidates on November 8, 2022. In the redistricting process, the district lines were changed during a contentious process in which one of the candidates, Johnny Khamis, threatened to sue for alleged gerrymandering.
