1937 Carmarthen Rural District Council election

There were no boundary changes at this election.

As was usual in rural Wales during the inter-war period, the election was largely fought on a non-political basis. Twenty candidates were returned unopposed; nineteen of whom were Independent candidates.^[2] Gwilym Rees, who had won the Llanddarog ward for Labour in 1934 was also returned unopposed. The only other Labour candidates defended seats at Llanarthney and Llangyndeyrn.

The first election to the enlarged council, following the amlagmation of Whitland RDC provided few surprises. The most noted result was the defeat of Hannah Mary Rees, the only woman member, at Whitland. She was defeated by W.S. Cole, a past chairman of the Whitland RDC. At Llanarthney, Thomas Thomas, a former Labour chairman of the council, who had lost his seat in 1931, was returned at the head of the poll.
