Che Puan Besar Hajah Haminah binti Haji Hamidun (Jawi: چئ ڤوان بسر حاجة همينة بنت حميدون), formerly known as Sultanah Haminah (born Haminah binti Hamidun; 15 July 1953) is the former Sultanah of Kedah and the widow of Sultan Abdul Halim Mua'dzam Shah. Born as a commoner, she married Sultan Abdul Halim on 25 December 1975 as his second wife. She served as the 14th Raja Permaisuri Agong (Queen 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.
