An election to the Llandeilo Rural District Council in Wales was held on 1 April 1935.[1] The election was held following the merger of the Llandeilo and Llandovery rural districts and the need to reduce the total number of members on the new authority. Following a recommendation made in 1932, it was decided that the rural districts of Llandeilo and Llandovery would be merged.[2] Elections were held in wards that had been amalgamated and also in wards where the number of councillors had been reduced.
It was preceded by the 1934 election and followed by the 1937 election which would be the first time that a whole council would be elected for the merged authority.
