Knight Leontiy Vassilievich Spafaryev (1765 - 30 January 1847) was a Lieutenant General of the Imperial Russian Navy. Spafaryev was Director of the Lighthouse Administration and cartographer of the Russian Admiralty.
Spafariev was an important contributor to the improvement of navigation along the Russian coasts. The first lighthouses in Russia were built during tsar Peter the Great's drive for reform and modernization at the beginning of the 18th century. However, it was only until the Administration of Lighthouses was created in 1807 that the Russian lighthouse system followed an organized pattern, becoming effective and efficient. This office was established by the Russian Navy and it began under the leadership of Leontiy V. Spafaryev.
As a cartographer, perhaps his most outstanding work is the 'Atlas of the Gulf of Finland', published in 1817. His name is spelt as 'Spafarief' or 'Spafarieff' in the United States.

Polsk officer. Redan 1813 var han ute i fält som underofficer, kastade sig sedan över militära och matematiska studier, och blev 1822 lärare vid artilleriskolan i Warszawa. 1830 var han på nytt ute i fält som kapten och tvingades därefter gå i landsflykt. Under några år vistades han i Frankrike och England och kom 1835 till Norge. Där blev han efter hand betrodd med olika offentliga ingenjörsarbeten, speciellt i 'Vassdragsvesenet', och blev 1846 anställd som kanaldirektör. Bland hans stora arbeten kan nämnas kanalen vid Moss. 1848 sade han upp sig från sitt arbete och reste till Paris för att deltaga i polackernas frihetskamp. Efter en tid återvände han till Norge och blev på nytt anställd inom kanal- och havsväsendet. 1855 kallade hans landsmän åter på honom och han lämnade då Norge för gott. Han blev senare lärare vid olika krigsakademier. Han lyckades aldrig återse sitt hemland.
