Geoffrey John Kirkby (26 August 1918 – 24 October 1998) was an officer in the Royal Navy during the Second World War, serving mainly at sea in small ships.

[1] Aged 21, Kirkby was awarded the Distinguished Service Cross (DSC) for boarding the sinking Italian Navy submarine Torricelli and capturing the vessel's signal books.

Kirkby, while still serving on board Kingston, took part in the Second Battle of Sirte, where Rear-Admiral Vian defended a Malta convoy against a far superior Italian force.

Kingston took part in a torpedo raid, for which the ship had to close within three miles of the Italian heavy units, and which led to the award of Kirkby's second DSC.

[citation needed] Kirkby received a Commander of the Order of the British Empire in 1968.
