The 2020 Georgia State Senate election was held on November 3, 2020. Georgia voters elected state senators in all 56 of the state senate's districts to the 156th Georgia General Assembly for two-year terms in the Georgia State Senate. The elections coincided with the 2020 United States presidential election, 2020 United States House of Representatives elections, 2020 Georgia House of Representatives election, and more.
Democrats flipped one seat, while Republicans retained majority control of the chamber.
Seats where the margin of victory was under 10%:
Incumbent senator Nikema Williams resigned to run for Georgia's 5th congressional district, which John Lewis had represented until his death. A special primary took place on November 3, 2020, and a runoff took place December 1, 2020. No Republican had filed to face Williams in the general election, so the special primary acted as the general election.
