Narcisse Virgilio Díaz de la Peña (20 August 1807–18 November 1876) was a French painter of the Barbizon school.
Diaz was born in Bordeaux to Spanish parents. At the age of ten, Diaz became an orphan, and misfortune dogged his early years. His foot was bitten by a reptile in Meudon wood, near Sèvres, where he had been taken to live with some friends of his mother. The bite was poorly dressed, and ultimately he lost his leg. However, as it turned out, the wooden stump that replaced his leg became famous.
