2023 Ogun State gubernatorial election

The 2023 Ogun State gubernatorial election took place on 18 March 2023, to elect the Governor of Ogun State, concurrent with elections to the Ogun State House of Assembly as well as twenty-seven other gubernatorial elections and elections to all other state houses of assembly. The election — which was postponed from its original 11 March date — was held three weeks after the presidential election and National Assembly elections. Incumbent APC Governor Dapo Abiodun won election to a second term by a 2.2% margin of victory over PDP nominee Oladipupo Olatunde Adebutu, a former House of Representatives member.

The primaries, scheduled for between 4 April and 9 June 2022, resulted in Abiodun being renominated by the All Progressives Congress on 26 May while for the Peoples Democratic Party, two separate parallel primaries were held on 25 May with one primary nominating Adebutu while the other primary picked Segun Sowunmi. The national PDP recognized the Adebutu-won primary in July 2022; however, that primary was annulled by a Federal High Court on 28 September. A Court of Appeal judgment on 28 November overturned the High Court ruling, reinstating Adebutu as the legitimate PDP nominee.

On 21 March, INEC declared Abiodun as the victor with official totals showing him winning about 276,000 votes (~43% of the vote) to defeat Adebutu with about 263,000 votes (~41% of the vote) and Otegbeye, who won around 95,000 votes (~15% of the vote). Due to alleged irregularities, Adebutu rejected the results and filed a challenge at the electoral tribunal. The legal case eventually reached the Supreme Court, which upheld the election of Abiodun in a January 2024 judgment.
