The second election to the Carmarthen Rural District Council was held in April 1898.
The successful candidates were also elected to the Carmarthen Board of Guardians.
There were unopposed returns in most wards at this election with some candidates withdrawing soon after nomination day to remove the need for a contest.
In addition six members were elected to represent the borough of Carmarthen.
In 1898 all the sitting members were returned unopposed.
