2024 Seanad by-election
A by-election was due to be held for a vacancy in Seanad Éireann on Monday, 29 April 2024. The vacancy was caused by the resignation for health reasons of Sinn Féin's Niall Ó Donnghaile from the Administrative Panel on 22 January 2024. At the close of nominations on 22 March 2024, only one candidate had been nominated, and Mal O'Hara of the Green Party was deemed elected unopposed.
