2023 Nigerian Senate elections in Ogun State

In the previous Senate elections, none of the three incumbent senators were returned with all three retiring at the end of their terms. In the Central district election, Ibikunle Amosun (APC) gained the seat for the APC with 49% of the vote while Ramoni Olalekan Mustapha (APC) won the East district with 44%. In the West district, Tolu Odebiyi (APC) won the race with just 29% of the vote. The senatorial results were a continuation of APC control in the state as the party also won most House of Representatives seats, won a majority in the House of Assembly, and won the gubernatorial election along with Buhari winning the state in the presidential election.

The Ogun Central Senatorial District covers the local government areas of Abeokuta North, Abeokuta South, Ewekoro, Ifo, Obafemi Owode, and Odeda. Incumbent Ibikunle Amosun (APC) was elected with 48.5% of the vote in 2019. In April 2022, Amosun announced that he would run for president instead of seeking re-election;^[10] however, Amosun withdrew on the date of the APC primary in favour of eventual nominee Bola Tinubu.^[11]

The Ogun East Senatorial District covers the local government areas of Ijebu East, Ijebu North, Ijebu North East, Ijebu Ode, Ikenne, Odogbolu, Ogun Waterside, Remo North, and Sagamu. Incumbent Ramoni Olalekan Mustapha (APC), who was elected with 44.2% of the vote in 2019, initially sought re-election but withdrew from the primary.^[12]
