Elections to the United States Senate will be held on November 3, 2020, with the 33 Class 2 seats of the Senate being contested in regular elections. The winners will be elected to six-year terms extending from January 3, 2021, until January 3, 2027. Additionally, there will be a special election in Arizona to fill the vacancy created by the death of John McCain in 2018.

In 2014, the last regularly-scheduled elections for Class 2 Senate seats, the Republicans won a net gain of nine seats from the Democrats and gained a majority in the Senate. Republicans defended that majority in 2016 and 2018, and held 53 Senate seats following the 2018 elections. Democrats held 45 seats after the 2018 elections, while independents caucusing with the Democratic Party held 2 seats.

Partisan composition

As of November 2018 (and including the 2020 special election in Arizona), Republicans are expected to defend 22 seats in 2020, while the Democratic Party is expected to defend only 12 seats. These figures could change if vacancies or party switches occur. Additional special elections may also be held in 2020 if vacancies should arise in Class 1 or Class 3 Senate seats.

  • "tossup": no advantage
  • "tilt" (used sometimes): advantage that is not quite as strong as "lean"
  • "lean": slight advantage
  • "likely" or "favored": significant, but surmountable, advantage
  • "safe" or "solid": near-certain chance of victory

    If the Democrats do win the vice presidency and the two Independents continue to caucus with them, then they will need a three seat gain to take control of the Senate.
