The 2024 Irish general election to elect the 34th Dáil took place on Friday, 29 November 2024, following the dissolution of the 33rd Dáil on 8 November by President Michael D. Higgins at the request of Taoiseach Simon Harris. Polls were open from 7 a.m. to 10 p.m UTC. It elected 174 Teachtaí Dála (TDs) across 43 constituencies of between 3 and 5 seats to Dáil Éireann, the lower house of the Oireachtas, Ireland's legislature. Under the Electoral (Amendment) Act 2023, the number of TDs was increased from 160 to 174, making it the largest Dáil in the history of the state, with an increase in the number of constituencies from 39 to 43. The main issues in the campaign were the cost of living, housing affordability and availability, immigration and asylum management, and economic stability amid external trade uncertainties, reflecting voter concerns despite the country's strong overall financial health.

The election resulted in Fianna Fáil remaining as the largest party, increasing its number of seats to 48. Its governing partner Fine Gael won 38 seats, with the two parties combined winning 86 seats, two shy of a majority. The Green Party, the third party of government, lost all but one of its seats, with only leader Roderic O'Gorman returning to the Dáil. Sinn Féin remained as the second largest party, winning 39 seats, while the Social Democrats and Labour each won 11 seats, an increase of five each.

On 15 January 2025, the formation of a coalition government was agreed between Fianna Fáil, Fine Gael, and nine independents. Micheál Martin was appointed Taoiseach on 23 January 2025.

The 33rd Dáil first met on 20 February 2020, and could have been dissolved no later than 19 February 2025. This meant that, per a calculation in The Irish Times, the latest date the election could have been held was 22 March 2025.

In June 2020, Fianna Fáil, Fine Gael and the Green Party formed a coalition government. The parties agreed on a rotation, with the two major party leaders alternating as Taoiseach. Micheál Martin, leader of Fianna Fáil, served as Taoiseach from 27 June 2020 to 17 December 2022; Leo Varadkar, leader of Fine Gael, served as Taoiseach from 17 December 2022 to 9 April 2024; and Simon Harris served as Taoiseach from 9 April 2024, shortly after succeeding Varadkar as Fine Gael leader.

For most of 2024, many pundits believed that an autumn election was likely; coalition leaders repeatedly said they would like the government to complete its full term but were open to an early election if the circumstances provided for it. Polling conducted in October 2024 indicated a majority of the public supported an early election to be held in November of the same year.

Following the announcement on 1 October 2024 of the 2025 budget, speculation began in earnest that an election would be called for November or December. In late October, Harris said that he expected the election to be held before the end of 2024. On 6 November, Harris confirmed that he would seek a dissolution of the Dáil on 8 November. Two days later, he asked the president to dissolve the Dáil. Later that day, Darragh O'Brien, the Minister for Housing, Local Government and Heritage, signed the order for the election to take place on 29 November 2024 and a three-week election campaign began.

To stand for election to Dáil Éireann, candidates must be Irish citizens aged at least 21, and if unaffiliated with a registered political party, they must secure either 30 assentors from the constituency or lodge a €500 deposit.
