2019 Nauruan parliamentary election

Parliamentary elections were held in Nauru on 24 August 2019. President Baron Waqa lost his seat in Boe Constituency, making him ineligible for a third term. Following the elections, Lionel Aingimea was elected President, winning a parliamentary vote 12–6 against David Adeang.

Electoral system
The 19 members of Parliament were elected from eight multi-member constituencies using the Dowdall system, a version of ranked voting; voters rank candidates, with the votes counted as a fraction of one divided by the ranking number (e.g. a candidate ranked second will be scored as ½); the candidates with the highest total were elected.

Conduct
Speaker Cyril Buraman issued a notice in the Republic of Nauru Government Gazette on 15 July 2019 announcing the date of the general election was 24 August. The 2019 general election was observed by two international organizations: the Pacific Islands Forum and the Commonwealth Secretariat.

Results
Out of 7,508 registered voters, 7,167 cast a vote, resulting in a turnout of 95.46%. 7,037 votes were valid and the remaining 130 either blank or invalid.

Ubenide
There was a recount in the Ubenide Constituency after six ballot papers were found in the Nauruan parliament chamber. The results were ultimately unchanged.

Presidential election
Following the elections, the newly elected MPs elected the president, who was required by the constitution be a member of parliament. Incumbent president Baron Waqa lost his seat in parliament, which meant he was ineligible. Lionel Aingimea defeated David Adeang of Nauru First by twelve votes to six.
