Pete Sutherland handily defeated John Martin in Tuesday's race for Nicholasville mayor.
With all precincts reporting, Sutherland had 5,076 votes to Martin's 2,655 in the unofficial tally.
Sutherland, 59, has been a city commissioner since 2011. Martin, 74, was mayor from 2003 to 2006.
"We are so excited. We're thrilled and looking forward to getting to work and doing a great job," Sutherland said.
Sutherland said he thinks he won because "people are happy with the direction that the city has been going in. ... They're looking forward to stay the course and keep moving forward."
Sutherland, a former co-owner of Sutherland Chevrolet in Nicholasville, will succeed Russ Meyer as mayor of Kentucky's 11th-largest city by population.
Meyer, a Democrat, defeated Jonah Mitchell, a Republican, in the race for state representative in the 39th District House seat that is now held by Bob Damron.
Damron ran for Jessamine County judge-executive but was defeated by David K. West.
