Lieutenant General Sir Denis John Charles Kirwan Bernard, KCB, CMG, DSO (22 October 1882 – 25 August 1956) was a British Army officer who commanded the 3rd Infantry Division shortly before the outbreak of World War II.

[4][5] He fought in World War I as a River Transport Officer with the British Expeditionary Force and then served in France, Gallipoli, Salonika and Egypt.

[5] He was made a GSO2 in November 1915[6] and succeeded Brigadier General John Duncan as a GSO1 in April 1916.

[5][8] While serving as Governor he had to consider proposals for American military bases there: these proposals were bitterly opposed by the local people at the time despite the war-time needs of the American military[9] and he resigned at the request of the British Government in 1941 "to make way for a civilian".

[11] His family home was Castle Hacket House in Galway,[12] where he died in 1956, aged 73.
