Pembrokeshire County Council (Welsh: Cyngor Sir Penfro) is the local authority for the county of Pembrokeshire, one of the principal areas of Wales.

Since the 2017 election the council has been led by a coalition of some of the independent councillors, Labour, Plaid Cymru and the Liberal Democrats, with the same coalition continuing following the 2022 election.^[3]

The first election to the modern council was held in 1995, initially operating as a shadow authority before coming into its powers on 1 April 1996. Independent councillors have held over half the council's seats ever since 1996:

Different groupings have formed among the independent councillors at different times, sometimes forming administrations with councillors from political parties. Between 1996 and 2017 the leader of the council came from the "Independent Political Group" (later called the "Independent Plus Political Group"). That group's numbers were reduced from 33 to 13 at the May 2017 election. Its leader Jamie Adams blamed the poor performance at that election on the IPPG's close connections to the council's discredited former chief executive.^[4][5]

Since the last boundary changes in 2022 the council has comprised 60 councillors, representing 59 wards. The ward of Pembroke: Monkton and St Mary South elects two councillors, the rest elect one councillor.^[14]

When created in 1996 the council inherited offices from the two predecessor authorities: Cambria House in Haverfordwest from Preseli Pembrokeshire District Council and Llanion Park in Pembroke Dock from South Pembrokeshire District Council, along with the former County Offices of Dyfed County Council on St Thomas's Green in Haverfordwest. The first meeting of the new authority was held at Shire Hall, Haverfordwest, which had been the meeting place of the pre-1974 Pembrokeshire County Council.^[16] Subsequent meetings were held at Cambria House. It was decided shortly after the new council's creation to build a new headquarters adjoining Cambria House. The new building was named County Hall, with the first full council meeting in the new building being held in October 1999.^[17] Cambria House was demolished shortly afterwards. The new County Hall was formally opened by Queen Elizabeth II on 22 November 2001.^[18]
