The second election to Dyfed County Council was held in May 1977.[1] It was preceded by the 1973 election and followed by the 1981 election. There were a number of unopposed returns, particularly in rural parts of the county.
The main feature of the results in Carmarthenshire was a Plaid Cymru challenge to Labour in the more urban part of the county although they lost the one seat they held on the previous council.
