The seventh election to the Carmarthenshire County Council was held in March 1907. It was preceded by the 1904 election and followed by the 1910 election.
The Liberals retained a strong majority. With a few exceptions, members were returned unopposed.
There were minor boundary changes leading to the creation of two additional wards, namely Ammanford and Llandissilio. The new Ammanford ward, which comprised the urban district of Ammanford was created by the division of the Bettws Ward into two. Significant population growth had taken place in the eastern part of the county as a result of the growth of the anthracite coal trade but demands for further additional wards to be formed in the Llanelli district were rejected. The second new ward was at Llandissilio in the western part of the county, on the Pembrokeshire border. It was formed out of portions of the existing Whitland and Llanboidy wards. There was less unanimity in favour of the new Llandissilio ward than was the case at Ammanford, and there were suggestions that an additional rural ward was being created to counterbalance the new industrial ward at Ammanford. A proposal for a third new ward, at Newchurch on the outskirts of Carmarthen was rejected in due course.
As a result of these boundary changes, the Council included 53 elected members as opposed to 51 previously. The number of aldermen remained at 17.
