Jefferson County Council

Every member of the Jefferson County Council, as the county's own website lists them.

The Jefferson County Council is Jefferson County's governing body. Its 7 members are elected from districts. The county executive, Dennis Gannon, is elected by the whole county and is not a member of the council. This page lists every seat and who holds it as Jefferson County's own website (jeffcomo.gov) lists them, read on October 28, 2026, and the map's County card reads the same list, because the county keeps its own page up to date between editions of the Secretary of State's Missouri Roster.

Opens the map with the county layer on, whose card lists every member of the council. This app does not draw Jefferson County's council district lines yet.

districtry is an independent, unofficial civic reference. It never guesses at who holds a seat: every name above is printed in the Missouri Secretary of State's Missouri Roster or on the county's own website, and where neither names anyone this page says so rather than filling the gap.
