Wrexham County Borough Council (Welsh: Cyngor Bwrdeistref Sirol Wrecsam) is the governing body for Wrexham County Borough, a principal area with city status in north Wales, covering Wrexham and the surrounding area.

Wrexham County Borough Council was created in 1996 under the Local Government (Wales) Act 1994. The new county borough of Wrexham covered all of the district of Wrexham Maelor and a small part of the Glyndŵr district, both of which were part of the county of Clwyd. On 1 April 1996 the new Wrexham County Borough Council took over the county-level functions previously performed by Clwyd County Council and the district-level functions from the two district councils, which were abolished.

On 1 September 2022 the county borough was awarded city status, but the council continues to style itself "Wrexham County Borough Council".

In November 2023, a councillor's annual basic salary was £17,600, with the council proposing an increase of 6% to £18,666.

The council has been under no overall control since 1999. Since the 2022 election the council has been led by a coalition of the "Independent Group", comprising 21 of the independent councillors, and the Conservatives. The council's one Liberal Democrat councillor joined the administration in December 2022.

The first election to the new council was held in 1995, initially operating as a shadow authority before coming into its powers on 1 April 1996. Political control of the council since 1996 has been as follows:
