An election to the Carmarthenshire County Council was held on 9 April 1970.
The final elections to the council before dissolution saw the Independents retain control of the authority.
The Plaid Cymru advance which was apparent in 1967 was halted and most candidates made little impact.
Contests took place in the majority of wards, and Labour lost some further ground in the Llanelli area while at the same time winning back some seats lost three years previously.
Aldermen were elected by the council, and served a six-year term.
