Sher Ali Afridi (died 11 March 1872) was an Indian soldier of Pashtun background, convicted of murder and imprisoned at the penal colony of Port Blair, Andaman Islands.

[5] Sher Ali, who belonged to the Kuki Khel Afridi Pashtun tribe, worked for the colonial government in the Punjab Police in the 1860s.

[8] He worked under Major Hugh James as a cavalry trooper in Peshawar and as a mounted orderly for Reynell Taylor, who awarded Sher Ali with a horse, pistol and certificate.

[9] In 1867, he killed Hyder who was one of his enemies at Peshawar (Indian territory where British jurisdiction applied) in broad daylight for alleged molestation of his sister.

[6] On 8 February, when the Viceroy had almost completed his inspection and was returning at 7:00 PM to his boat, where Lady Mayo was also waiting, Sher Ali Afridi appeared from the dark and stabbed him.

[9] Sher Ali Afridi wanted to kill two British people, the Superintendent and the Viceroy, as a revenge for his sentence, which he thought was more severe than he deserved.
