Geoff Duncan

Geoffrey L. Duncan (born April 1, 1975) is an American politician, businessman, and public speaker. A Republican, he served as the 12th lieutenant Governor of Georgia from 2019 to 2023. Duncan is a former member of the Georgia House of Representatives.

After playing college baseball for the Georgia Tech Yellow Jackets, Duncan played professional baseball for six years, until a shoulder injury ended his baseball career. He went into business and was elected to the Georgia House in 2012. Duncan was elected lieutenant governor in 2018, but he did not seek re-election in 2022, with fellow Republican Burt Jones being elected to replace him.

In the wake of the 2020 presidential election, Duncan was among the few Republican Party officials who openly and outspokenly criticized Donald Trump for falsely claiming the election was stolen. After leaving office, Duncan became a political commentator for CNN.

In January 2025, the Georgia Republican Party's executive committee passed a resolution to expel Duncan from the state party and ban him from running as a Republican, a largely ceremonial statement as Georgia does not have partisan registration nor do political parties have the power to unilaterally strip partisan affiliation from somebody. Duncan has stated that he still considers himself a Republican.
