An election to Carmarthen District Council was held on 2 May 1991.[1] It was preceded by the 1987 election and followed, after local government reorganization, by the first election to Carmarthenshire County Council in 1995. On the same day there were elections to the other district local authorities and community councils in Wales.
There were some limited changes as a result of the election, including the capture of three seats by the Labour Party in Carmarthen Town.
An Independent candidate had won a seat at a by-election following the resignation of Plaid Cymru councilor Malcolm Jones.
