Sir Leicester Smyth KCB KCMG (born Curzon-Howe; 25 October 1829 – 27 January 1891) was a British Army officer and colonial administrator who served as the Governor of Gibraltar.

[1] In 1877 he became General Officer Commanding Western District and in 1880 GOC Cape Colony.

[1] He was acting High Commissioner for Southern Africa from 1882 to 1883, GOC Southern District from 1889 to 1890 (in which capacity he hosted a visit by the Shah of Persia[2]) and Governor of Gibraltar from 1890 until his death in 1891, aged 61.

[1] During the Second Boer War, in February 1900, it was claimed that in 1884 Smyth refused a request from Colonel Luard, who was commanding the Royal Engineers, to map the Drakensberg passes.

The lack of adequate maps severely hampered British efforts during the war.
