2016 United States Senate election in Georgia

The 2016 United States Senate election in Georgia was held November 8, 2016, to elect a member of the United States Senate to represent the State of Georgia, concurrently with the 2016 U.S. presidential election, as well as other elections to the United States Senate in other states and elections to the United States House of Representatives and various state and local elections. The primary election for the Republican and Democratic parties took place on May 24, 2016.

Incumbent Senator Johnny Isakson won re-election to a third term in office by a wide margin. He later resigned from the Senate on December 31, 2019 due to health issues. As of 2024, this remains the last time Republicans won a Senate election in Georgia, as well as the last time that suburban Gwinnett and Henry counties have voted Republican in a statewide election. It also remains the last time that any statewide candidate has won an election in Georgia by double digits, and the last time that any U.S. Senate candidate in Georgia has won without a runoff. This is the most recent and the last United States Senate election in Georgia in which the winning candidate won a majority of Georgia's counties.
