The 1870 Dublin City by-election was fought on 18 August 1870.
The by-election was fought due to the void election of the incumbent MP of the Conservative Party, Sir Arthur Edward Guinness.
[1] It was won by the Liberal candidate Sir Dominic John Corrigan.
[2] Corrigan did not stand for re-election in 1874; his support for temperance and Sunday closing (of pubs) is thought to have antagonised his constituents and alcohol companies.
