The 2019 Nigerian Senate election were held in all 109 senatorial districts where voters elected senators using first-past-the-post voting. Most elections were held on February 23, 2019, with some elections running into February 24 while others had supplementary or rerun elections that took place at a later date. The last regular senatorial elections for all districts were in 2015.
As is common after Nigerian elections, a swarm of ligation followed the senatorial races with court and tribunal decisions changing results in the districts of Ekiti South,[c]Niger East,[k] and Sokoto South[l] along with one ruling changing all three Zamfara elections[m] and a rerun election being called in Kogi West. The Akwa Ibom North-West election was also annulled, albeit only in certain polling units, and a 2020 supplementary election held which confirmed Akpabio's loss. Prior to the elections, all Rivers State APC nominees were disqualified barring two incumbent senators running for reelection from contesting.[n]
