The 1918 United States Senate elections were held throughout 1918, the midpoint of Woodrow Wilson's second term as president. This was the first election since the ratification of the 17th Amendment that all 32 Class 2 senators were subject to direct or popular election, making them the final class under the old system of being selected by state legislatures. Special elections were also held to fill vacancies.
Republicans gained a slim 2-seat control after picking a net of 6 seats up. This came after an April 1918 special election where they flipped a seat in Wisconsin.
Three Republicans and one Democrat retired instead of seeking re-election. Two Republicans retired instead of seeking election to finish the unexpired terms, one Democrat retired instead of seeking election to a full term and two Democrats retired instead of seeking election to finish the unexpired terms.
Eight Democrats and one Republican sought re-election but lost in the primary or general election.
One Democrat died on October 21, 1917, and his seat remained vacant until an April 1918 election.
