The 2020 Alaska State Senate elections are taking place as part of the biennial 2020 United States elections. Alaska voters will elect state senators in 11 of the state's 20 senate districts – the usual ten plus one special election. State senators serve four-year terms in the Alaska Senate, with half seats up for election every two years. The primary elections on August 18, 2020, will determine which candidates will appear on the November 3, 2020, general election ballot.
