Sir Thomas Theophilus Metcalfe, 4th Baronet, KCB was an East India Company civil servant and agent of the Governor General of India at the imperial court of the Mughal Emperor Bahadur Shah Zafar.

Bahadur Shah II (born Mirza Abu Zafar Siraj-ud-din Muhammad, usually referred to by his poetic title Bahadur Shah Zafar, was the twentieth and last Mughal emperor and an Urdu poet. He was the second son and the successor to his father, Akbar II, who died in 1837. He was a titular Emperor, as the Mughal Empire existed in name only and his authority was limited only to the walled city of Old Delhi. Following his involvement in the Indian Rebellion of 1857, the British deposed him and exiled him to Rangoon in British-controlled Burma in 1858, after convicting him on several charges. The title of Empress of India was subsequently assumed by Queen Victoria.
