Leonardo de Mango (19 February 1843 – 1930) was an Italian painter active for most of his career in Istanbul, depicting Orientalist themes.
He was described by the art commentator Thalasso as a painter through whom the East spoke.
The eldest child of a large family, de Mango was born in the town of Bisceglie near Bari in Italy, where he honed his native talent for drawing up to the age of nineteen.
