Jean Étienne de Boré (27 December 1741 – 1 February 1820) was a Creole French planter, born in Kaskaskia, Illinois Country, who was known for producing the first granulated sugar in Louisiana. At the time, the area was under Spanish rule. His innovation made sugar cane profitable as a commodity crop and planters began to cultivate it in quantity. He owned a large plantation upriver from New Orleans. De Boré's plantation was annexed to the city of New Orleans in 1870, and is now the site of Audubon Park, Tulane University, and Audubon Zoo.
