Republican candidates Mayor Fred Cavanaugh and District 3 City Councilmember Don Sprawls are seeking re-election.
Mr. Cavanaugh has been mayor since 1991 and hopes for a fifth term.
"There's no doubt how I feel about Aiken," he said, having been on the city council for 21 years before he first ran for mayor. "I still have the same desire and hopes for the future."
Mr. Cavanaugh said he enjoys bringing different sides of an issue together.
"This is one of the bright spots in South Carolina as far as cities," he said. "That's proven by the people who want to move to Aiken."
City Councilmember Beverly Clyburn, a Democrat representing District 1, also filed for re-election and is seeking her seventh term.
Four years ago, all three ran unopposed in the general election.
People interested in running in the Republican primary can file at the Aiken County Republic Party Headquarters at 127 Greenville Street N.W.
Filing for the Democratic primary can be done at the Law Offices of Everett K. Chandler at 225 Chesterfield Street.
The primary elections will be held Sept. 18, and the general election will be held Nov. 6.
Residents wanting to vote in the upcoming elections must register 30 days before the primary.
