Sir Louis William Dane GCIE CSI (21 March 1856 – 22 February 1946) was an Anglo-Irish administrator during the time of the British Raj.

[1] He was born on 21 March 1856 at Chichester, Sussex, the fifth son of Richard Martin Dane, an army staff surgeon, and Sophia Eliza, the daughter of Colonel Charles Griffiths who had served in the First Anglo-Afghan War.

In 1904, the Dane Mission, named for his leadership, was sent by the British to Afghanistan to negotiate the friendship agreement with the country's new Amir, Habibullah Khan.

The mission resulted in a reinforcement of the agreements between the British and Abdur Rahman Khan, Habibullah's father and predecessor as Amir.

Dane's arm was broken by a bullet; Lawrence Dundas, formerly Secretary of State for India and Charles Cochrane, formerly governor of the Bombay presidency were slightly injured.
