The 2023 Nigerian Senate elections in Osun State will be held on 25 February 2023, to elect the 3 federal Senators from Osun State, one from each of the state's three senatorial districts. The elections will coincide with the 2023 presidential election, as well as other elections to the Senate and elections to the House of Representatives; with state elections being held two weeks later. Primaries were held between 4 April and 9 June 2022.
In the previous Senate elections, none of the three incumbent senators were returned with Olusola Adeyeye (APC-Central) and Babajide Omoworare (APC=East) losing renomination while Ademola Adeleke (PDP-West) retired. In the East district election, Francis Adenigba Fadahunsi gained the seat for the PDP with 50% of the vote while Ajibola Basiru (APC) retained the East district for his party with 54%. In the West district, Adelere Adeyemi Oriolowo (APC) gained the seat with 41% of the vote. The senatorial results were a continuation of slight APC control in the state as the party also won most House of Representatives seats and won a majority in the House of Assembly, in addition to Buhari winning the state in the presidential election.
