The Nelson Mandela Bay Municipality (Xhosa: uMasipala oMbaxa iNelson Mandela Bay; Afrikaans: Nelson Mandelabaai Metropolitaanse Munisipaliteit) is one of eight metropolitan municipalities in South Africa. It is located on the shores of Algoa Bay in the Eastern Cape province and comprises the city of Gqeberha, the nearby towns of Uitenhage and Despatch, and the surrounding rural area.

The name "Nelson Mandela Bay Metropolitan Municipality" was chosen to honour former President Nelson Mandela.

Bricks used in the Nelson Mandela Bay Metropolitan Municipality around 1903-04 may have been made from parts of the holotype of the sauropod dinosaur Algoasaurus bauri.

Established on 5 December 2000, the Nelson Mandela Bay Metropolitan Municipality was formed as an administrative area covering Port Elizabeth (Gqeberha), the neighbouring towns of Kariega (Uitenhage) and Despatch and the surrounding agricultural areas. Thus included the following cities/towns/villages:

Beachview Bethelsdorp Colchester Despatch iBhayi KwaNobuhle

Motherwell New Brighton Port Elizabeth Seaview Swartkops Uitenhage

The municipal council consists of one hundred and twenty members elected by mixed-member proportional representation. Sixty councillors are elected by first-past-the-post voting in sixty wards, while the remaining sixty are chosen from party lists so that the total number of party representatives is proportional to the number of votes received. In the local government election of 1 November 2021, no party obtained a majority on the council again. The African National Congress managed to form a minority coalition government to govern the municipality. Former councillor and businesswoman Eugene Johnson of the ANC was elected mayor on 22 November 2021, in a coalition consisting of the parties: GOOD, AIM, UDM, DOP, Northern Alliance, Patriotic Alliance and the PAC. She won against the DA's mayoral candidate, Nqaba Bhanga, by 1 vote, as a DA councillor was absent.

During a council meeting on 21 September 2022, Johnson was removed as mayor through a vote of no confidence and succeeded by the DA's Retief Odendaal. Odendaal was, in return, removed as mayor in a vote of no confidence and replaced with council speaker Gary van Niekerk on 26 May 2023.
