The 2017 United States state legislative elections were held on November 7, 2017. Three legislative chambers in two states held regularly scheduled elections. These off-year elections coincided with other state and local elections, including gubernatorial elections in two states.
Democrats won control of the Washington Senate through a special election for a seat previously held by a Republican, ending Republican-led coalition control there. Meanwhile, in regularly scheduled elections, Democrats maintained control of the New Jersey legislature and narrowed Republican control of the Virginia House of Delegates.
