Vice-Admiral John George Lawrence Dundas, (3 November 1893 – 26 March 1952) was a Royal Navy officer who served as the Assistant Chief of the Naval Staff from 1944 to 1945.
Born on 3 November 1893, Dundas was the son of the Hon. Cospatrick Thomas Dundas, DL, JP (1862–1906) and his wife Maud FitzWilliam (1871–1949), a daughter of the Hon. George Wentworth-FitzWilliam and a granddaughter of the 5th Earl FitzWilliam. Dundas's father was a grandson of the 1st Earl of Zetland and, when his elder brother inherited the earldom in 1873, Cospatrick was afforded the style of a peer's younger son. After his death in 1906, Maud remarried (in 1912) to the army officer and colonial administrator Major Sir Harry Edward Spiller Cordeaux.[1]

Several months into the Second World War, he was given command of the light cruiser (1940–1942),[6] and was involved in escorting the Russian convoys.
