She served as the 14th Raja Permaisuri Agong (Queen consort) of Malaysia from 2011 to 2016, during her husband's second term as Yang di-Pertuan Agong, the Malaysian federal head of state. After her husband's death in September 2017, his successor and her brother-in-law Sultan Sallehuddin, bestowed upon her the title Che Puan Besar of Kedah, roughly equivalent to the queen dowager.

Upon the installation of HRH Sultan Abdul Halim as HM The Yang di-Pertuan Agong XIV on 13 December 2011, HRH Sultanah Hajah Haminah became HM The Raja Permaisuri Agong of Malaysia.[3] HM Tuanku Hajah Haminah then became the fourth commoner who becomes the Raja Permaisuri Agong after Tuanku Bainun of Perak, Tuanku Siti Aishah of Selangor and Tuanku Nur Zahirah of Terengganu.
