Colonel John Duncan Grant VC, CB, DSO (28 December 1877 – 20 February 1967) was a British Indian Army officer who was awarded, on 24 January 1905, the only Victoria Cross for action in the Tibet Campaign, for action at the highest altitude in the Victoria Cross's 165-year history: that of the Tibetan Plateau which has an average height of around 15,000 feet.

Regardless of their injuries they again attempted to scale the breach, and, covered by the fire of the men below, were successful in their object, the Havildar shooting one of the enemy on gaining the top.

The successful issue of the assault was very greatly due to the splendid example shown by Lieutenant Grant and Havildar Karbir Pun.

He retired in 1929 with the rank of colonel and was appointed a Companion of the Order of the Bath in the King's Birthday Honours of that year.

[12] He died in Tunbridge Wells, aged 89, and was cremated and buried at the Kent and Sussex Crematorium and Cemetery.
