The 2020 United States Senate elections 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 also be two special elections: one special election in Arizona to fill the vacancy created by the death of John McCain in 2018 and one in Georgia following the resignation of Johnny Isakson at the end of 2019.
Including the special elections in Arizona and Georgia, Republicans will be defending 23 seats in 2020, while the Democratic Party will be defending 12 seats. Democrats will need to pick up three or four seats to gain a majority in the Senate, depending on which party wins control of the vice presidency.
