2021 Seanad by-elections

Two by-elections were held for vacancies in Seanad Éireann on Wednesday, 21 April 2021. The vacancies were caused by the resignations of Fine Gael's Michael W. D'Arcy from the Agricultural Panel in September 2020 to become chief executive of the Irish Association of Institute Management; and of Sinn Féin's Elisha McCallion from the Industrial and Commercial Panel in October 2020 due to a COVID-19 grants controversy. Fine Gael's Maria Byrne was elected to the Agricultural Panel, and Fianna Fáil's Gerry Horkan to the Industrial and Commercial Panel. Both were elected on the first count.
