2016 Indiana gubernatorial election
The 2016 Indiana gubernatorial election was held on November 8, 2016, to elect the Governor and Lieutenant Governor of Indiana, concurrently with the 2016 U.S. presidential election as well as elections to the United States Senate and elections to the United States House of Representatives and various state and local elections. The primaries were held on May 3, 2016. Republican Lieutenant Governor Eric Holcomb won the race with 51.4% of the vote.

Incumbent Republican Governor Mike Pence was running for reelection to a second term in office until July 15, 2016, when Republican presidential nominee Donald Trump selected Pence as his vice presidential running mate. As Pence was barred by Indiana law from simultaneously running for both offices, he subsequently withdrew from the gubernatorial election. Pence went on to become Vice President of the United States. He was replaced on the ballot for Governor by his former running mate, incumbent Lieutenant Governor Eric Holcomb, who was selected by the Indiana Republican State Committee as the nominee on July 26, 2016. Holcomb later selected State Auditor Suzanne Crouch on August 1, 2016, to be his running mate as the nomination for Lieutenant Governor was made vacant by the decision of Holcomb to seek the gubernatorial nomination; she was confirmed at a subsequent meeting of the Indiana Republican State Committee later that day.

John Gregg, the former Speaker of the Indiana House of Representatives, was the Democratic nominee. Gregg previously ran for Governor in 2012, but was defeated by Pence.

Results

Republican State Committee selection
On July 15, 2016, Donald Trump announced that Pence would be his running mate as vice president in the 2016 presidential election. Under Indiana law, Pence was unable to run for both governor and vice president simultaneously; he therefore withdrew from the gubernatorial election, creating a vacancy on the Republican ticket. On July 26, the chairman of the Indiana Republican Party, Jeff Cardwell, announced that Eric Holcomb had been nominated by the Indiana Republican State Committee to replace Pence on the ballot for Governor. The vote totals were not released. Holcomb later selected Suzanne Crouch on August 1, 2016, to be his running mate as the nomination for Lieutenant Governor was made vacant by the decision of Holcomb to seek the gubernatorial nomination; she was then confirmed by the Committee at a meeting later that day.
