Ghulam Husain Ali Khan (8 January 1748 – 15 July 1801) aka Ghulam Hussainy or Umdat ul-Umra, was the Nawab of the Carnatic state in the Mughal Empire from 1795 to 1801.
He was actually named by his grandfather, Anwaruddin Khan, as "Abdul Wali".
But he was subsequently renamed as "Umdat ul-Umara", after the name of the court of the Mughal Emperor Shah Alam II.
