An election to the Carmarthenshire County Council was held in March 1934. It was preceded by the 1931 election and followed by the 1937 election.
The Independent group remained the majority grouping on the Council, with Labour polling strongly in the industrial south and east of the county. In the Llanelli area, Communist Party candidates contested a number of seats but polled a low vote in all cases.
There were no boundary changes.
Only a minority of the 53 divisions were contested. Labour fielded 30 candidates, more than ever before; eleven of whom were returned unopposed.[1]
A greater number of contests took place in 1934 in Carmarthenshire than at any time since the First World War. This was as a result of more contests in rural areas between rival Independent candidates.
In addition to the 53 councillors the council consisted of 17 county aldermen. Aldermen were elected by the council, and served a six-year term. Following the elections the following nine aldermen were elected (with the number of votes in each case).
