Mariam Sangki-Mangudadatu is a Filipina politician who has been the chief executive of Maguindanao del Sur since its division from Maguindanao in 2022. Her position is currently disputed as her assumption as acting governor remains unrecognized by the Bangsamoro and national governments, the latter of which recognizes her only as the officer in charge of the province. Previously, she was the 11th and 1st female governor of Maguindanao, serving from 2019 to 2022.[1] [2] [3]
Sangki-Mangudadatu first entered politics in 2013 when she won as mayor of Datu Abdullah Sangki in Maguindanao.[4] Her opponent was Samsodhen Ampatuan-Sangki, a member of the Ampatuan clan.[5] She successfully won reelection in 2016.[6] In the 2019 general election, she ran as governor of Maguindanao where she eventually won becoming the first female governor of the province.

The former Maguindanao province was dissolved into two new provinces following the 2022 Maguindanao division plebiscite on September 17, 2022, and she was supposed to become acting governor of the new Maguindanao del Sur province.[7] However this was uncertain, since the relevant provision presumes that the plebiscite would be held before the May 2022 national elections but the division vote was postponed after that date.[8] [9] She assumed the position and took her oath as governor of the new province on October 13.[10]
She was named Officer in Charge (OIC) of the province on April 5, 2023 by President Bongbong Marcos in an attempt to resolve the uncertainty of leadership in the province.[11] She opposed the appointment as OIC, believing she has the mandate to be acting governor as per the province's charter law.[12] However, she took oath as OIC of the province on April 28, 2023.[13]
Sangki-Mangudadatu is married to Suharto Mangudadatu and they have three children, including Pax Ali.
