South Pembrokeshire (Welsh: De Sir Benfro) was one of six local government districts of Dyfed, Wales from 1974 to 1996.

However, in 1981, the communities of Bletherston, Clarbeston, Llandeilo Llwydarth, Llandissilio West, Llangolman, Llanycefn, Llys y Fran, Maenclochog, Mynachlog-ddu, New Moat and Vorlan were transferred to Preseli district.

The building had been built in 1904 as part of the Llanion Barracks, and had been acquired by the former Pembroke Borough Council in the early 1970s to serve as its headquarters, just a couple of years before that council's abolition.

[8] The first election to the council was held in 1973, initially operating as a shadow authority before coming into its powers on 1 April 1974.

Throughout the council's existence a majority of the seats were held by independent councillors.
