The seventeenth election to Glamorgan County Council, south Wales, took place in March 1946.
A number of long-standing members stood down including the Reverend William Saunders, who was not selected as a Labour candidate and Gwilym Davies (Dulais Valley).
Nine of the retiring aldermen sought re-election, the exceptions being the Rev William Saunders and Edgar Chappell.
[4] Dudley Howe had previously represented Cadoxton and gained the neighbouring Barry ward from Labour.
At Neath, Charles P. Huins held his seat with a majority which exceeded that gained by Alderman Degwel Thomas at the triennial election.
