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 Conservatives made a conscious attempt to contest far more seats than at recent elections in an election dominated by ongoing disputes over disestablishment. However, the Liberals retained a strong majority and many sitting 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.

Eighteen wards were contested, compared with only six in 1904.
Four of those elected at the first election in 1889, and who had served continuously since then, sought re-election. Earl Cawdor, Sir James Drummond, C.E. Morris and D.C. Parry (Llanelli) were all returned unopposed.
While a small number of wards were hotly contested and the Conservatives made a small number of gains, their attempt to change the political composition of the council was unsuccessful.
In Llanarthney, a determined attempt was made to unseat Henry Jones-Davies, with allegations that the Conservative David Farr Davies, a colliery manager, was supported by some labour figures.
