Ammanford Urban District Council was a former local authority in Carmarthenshire. It was established under the provisions of the Local Government Act 1894 in 1903 and comprised parts of the parishes of Llandybie and Betws. It was created specifically as a result of the rapid population growth in the town as a result of the expansion of the Welsh anthracite coalfield. The Council was abolished in 1974 and Ammanford became part of Dinefwr Borough Council
