An election to Llanelli Borough Council was held in May 1987. It was preceded by the 1983 election and followed by the 1991 election. On the same day there were elections to the other district local authorities and community councils in Wales.[1]
The Labour Party continued to hold the majority of seats following the election but following the boundary changes a number of seats were lost to other political parties and to Independents.
There were wholesale boundary changes and new wards created in place of the previous eleven three-member wards which were abolished.
