The fourth election to West Glamorgan County Council was held in May 1985.[1] It was preceded by the 1981 election and followed by the 1989 election.
Once again, the Labour Party fielded candidates in every ward. In addition to the Conservative Party and Plaid Cymru, a significant number of seats were contested by the SDP/Liberal Alliance. There were fewer Ratepayer candidates than at previous elections.
In the Neath area, Labour contested all thirteen seats, with Plaid Cymru running nine candidates.[2]
Labour retained their majority.
