Nawabzadi Umdatunnissa Begum (born as Princess Umdat-un-nissa Sultana of Singranatore; 1871–1912) was the queen consort of Nawab Syed Ahmed Hassan of Kharui Raj. She served as the regent of Kharui for 20 long years i.e. from 1892 to 1912. Nawab Begum gave up purdaah and went to the Court of Wards, Calcutta to fight against the arbitrary economic policies introduced by the British, because of which her estate had suffered severe losses. She challenged the British government in their own court and won the legal battle against them, making her one of the first woman royalties in British Bengal to do so.
