The 1875 Kilkenny City by-election was fought on 28 April 1875. This arose due to the death of the incumbent Home Rule MP, John Gray. It was contested by three candidates: Gray's son Edmund Dwyer Gray, Edward Marum, and Benjamin Whitworth, former MP for Drogheda. Gray told the electors that his programme did not differ substantially from that of Whitworth: he was in favour of "Home Rule, denominational education, fixity of tenure at fair rents, and reform of the Grand Jury Laws." Marum went on to be elected MP for County Kilkenny and Gray for County Tipperary.
