General Sir George Digby Barker GCB (Chinese Translated Name: 白加; 9 October 1833 – 15 April 1914) was a British soldier and colonial administrator.

[8] Under his command, the size of the garrison increased by 50 per cent in response to Governor Des Voeux's concerns about the defence of the colony.

[10] Upon Sir William Robinson's arrival to serve as Governor in December 1891, Barker recommended an extension of Hong Kong's northern frontier.

Barker was then appointed Governor and General Officer Commanding of the Imperial fortress colony of Bermuda, with its large garrison, in 1896[11] and retired in 1902.

One of their daughters, Helena Barker, married in 1891 Francis Henry May, who would become Governor of Hong Kong from 1912 to 1919.
