The twelfth election to Cardiganshire County Council took place in March 1925. It was preceded by the 1922 election and followed by the 1928 election. While the previous election had been held in the shadow of bitter Liberal infighting at parliamentary level, the temperature had cooled and only ten seats were contested. 
  Candidates
 The election saw only ten contests, compared with 24 three years previously.[1] With hindsight this can be seen as the start of half century of Independent domination in the local politics of Cardiganshire.[n 1] Although political affiliations were no longer a feature of most contests the split in the Liberal ranks between Coalition and Asquithian Liberals had largely disappeared and some individuals had drifted away from Liberalism towards the Conservatives (one example being Morgan Lloyd Williams at Ysbyty Ystwyth). 
 Retiring aldermen
 Eight aldermen retired, seven of whom were Liberals and one Conservative, R.S. Rowland of Gareth, Llangybi.[2] Two of their number, D.C. Roberts (who had previously contested his seat at Aberystwyth) and the sole Conservative sought election. 
The other retiring aldermen were the Rev. John Williams, Cardigan, who had not faced the electorate for many years; the Rev William Griffiths (New Quay), the Rev T. Mason Jones, (Devil's Bridge) and R.J.R. Loxdale (Llanilar) who last faced an election in 1913;  and John Morgan Howell (Aberaeron) and Thomas Davies (Newcastle Emlyn) who had been elected to fill vacancies in recent years. 
 Contested elections
 Only ten seats were contested and these were largely fought on non-political lines.[3] Two seats can be said to have changed hands but in both cases this resulted in the sitting member not seeking re-election. At Lampeter, J.C. Harford's seat was won by a Liberal and at Llangybi, the sitting Liberal stood down allowing Alderman R.S. Rowland, the Garth, to be returned unopposed. 
 Outcome
 Very little change resulted from the election of 1925. Three members of the originally elected council in 1889 remained as members, namely Aldermen John Morgan Howell, Peter Jones and C.M. Williams.

  Election of Aldermen
 Eight aldermen were elected, including one Conservative, Dr John Morgan, who replaced R.S. Rowland.[4] As well as Dr Morgan, Evan Lewis, Samuel Jones and D. Morgan James became new aldermen, while retiring alderman D.C. Roberts had yet again been returned unopposed at Aberystwyth. 
Of the three retiring aldermen re-appointed without facing the electorate, J.M. Howell had fought a contested election in 1922 and was re-appointed as alderman after the death of E. Lima Jones. Loxdale had last been returned unopposed in 1910 while the Rev. John Williams had not stood as a candidate since 1898.
