A Dáil by-election was held in the constituency of Dublin West in Ireland on Friday, 23 May 2014, to fill a vacancy in the 31st Dáil. It followed the resignation of independent Teachta Dála (TD) Patrick Nulty on 22 March 2014.

It was held on the same day as the 2014 European and local elections, and the Longford–Westmeath by-election.

The Electoral (Amendment) Act 2011 stipulates that a by-election in Ireland must be held within six months of a vacancy occurring.

Socialist Party candidate Ruth Coppinger was elected on the sixth count.

This was the second by-election in Dublin West during the 31st Dáil.
