The 2019 Nigerian gubernatorial elections were held for state governors in 31 out of 36 Nigerian states. All but three were held on 2 March 2019 with the election for Rivers State being postponed until 4 April, while the Kogi State and Bayelsa State elections were both held on 16 November. The last regular gubernatorial elections for all states were in 2015.

All states have a two term limit for Governors which made several incumbent governors ineligible for re-election. Seven APC governors were term-limited while eleven incumbent APC governors were eligible for re-election. Among PDP governors, three were term-limited while ten could seek re-election. Elections were held in 18 of the 22 states with APC governors and all 13 of the states with PDP governors. Incumbent state governors running to be reelected included 11 APC governors and 10 PDP governors.

The PDP picked up four governorships from the APC in Adamawa, Bauchi, Oyo, and Zamfara while the APC picked up two governorships from the PDP in Gombe and Kwara; net change was PDP+2. Court decisions changed results in several states with the APC winners in Bayelsa and Zamfara being disqualified prior to their inaugurations while the PDP's win in Imo State was overturned after the erstwhile winner governed for over seven months.

One-term PDP incumbent Okezie Ikpeazu sought re-election and won the PDP nomination while businessman Uchechukwu Sampson Ogah became his main opponent by winning the APC nomination. Ikpeazu won re-election, 60–23.

One-term APC incumbent Bindo Jibrilla sought re-election and won the APC nomination while former Acting Governor Ahmadu Umaru Fintiri became his main opponent by winning the PDP nomination. Fintiri defeated incumbent Jibrilla, 43–37.

One-term PDP incumbent Udom Gabriel Emmanuel sought re-election and won the PDP nomination while former managing director of the Niger Delta Development Commission Nsima Ekere became his main opponent by winning the APC nomination. Emmanuel won re-election, 75–25.

One-term APC incumbent Mohammed Abdullahi Abubakar sought re-election and won the APC nomination while former FCT Minister Bala Mohammed became his main opponent by winning the PDP nomination. Mohammed defeated incumbent Abubakar, 46–45.

Two-term PDP incumbent Henry Seriake Dickson was ineligible for re-election due to term limits. Businessman David Lyon won the APC nomination while Bayelsa Central Senator Douye Diri won the PDP nomination. Initial results showed Lyon defeating Diri, 71–29, but due to a false certificate from APC Deputy Governor nominee Biobarakuma Degi, Lyon was disqualified and Diri was declared winner.
