1937 Carmarthenshire County Council election

As in all previous inter-war elections, the Independent group won a majority of the seats and this majority was bolstered by holding the majority of the aldermanic seats also. By 1937 the Labour Party held almost all the seats in the industrial eastern part of the county.

There were a number of boundary changes at this election. In Carmarthen town the boundaries were redrawn, reducing the number of wards from four to three. In Llanelli, in contrast, the number of wards were increased from eight to nine following a similar process. An additional ward was also created in Ammanford and new wards at Pontyberem and Trimsaran.

Other wards were renamed or had their boundaries slightly altered.

Around half the wards were uncontested, mainly in the rural areas.

A similar number of contests took place compared with 1934. This included contests in rural areas between rival Independent candidates.

53 councillors were elected.

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).
