Caroline Yvonne Jones (born 1 April 1955) is a Welsh politician who was a Member of the Senedd (MS) for South Wales West from 2016 to 2021.

[14][15]As the lead UKIP candidate on the South Wales West list, she was elected as her party's sole representative in that region.

[20] In May 2018 it was revealed that Jones had failed to declare the employment of husband Alun Williams in her office on her register of interests.

[21] The following month, Jones was taken to court by former UKIP Chief of Staff Robin Hunter-Clarke for the wrongful termination of his contract.

The judge ruled that she could not grant interim relief because it was unclear who Mr Hunter-Clarke's employer was at the time of the sacking.

[2] On 18 August 2020, Jones released a statement stating that she had quit the Brexit Party's Senedd Group to sit as an Independent member due to its newly adopted anti-devolution stance.

[25] In mid October 2020 she formed a new group in the Senedd, the Independent Alliance for Reform, together with fellow MSs David Rowlands and Mandy Jones.

[29][30] In 2023, Jones joined Reform UK, and was later announced as the party’s candidate in Bridgend, ahead of the 2024 general election.
