Catherine Connolly secured 914,143 first preference votes, representing 63% of the 1,442,698 valid votes cast. She defeated Fine Gael's Heather Humphreys, who received 424,987 votes, or 29%.
Fianna Fáil's Jim Gavin, a political novice, won 103,568 votes, or 7%, after withdrawing from the campaign due to a financial scandal. The election saw 213,738 spoiled or invalid votes, an unprecedented number.
Connolly, a former barrister and clinical psychologist, was backed by a leftwing alliance and received endorsements from Labour and Sinn Féin. She will succeed President Michael D Higgins, who congratulated her in a phone call.
