Gustave Nadaud (20 February 1820 in Roubaix – 28 April 1893 in Passy) was a French songwriter and chansonnier.
Nadaud's first career was as an accountant; he took up songwriting as a hobby at age 28.
His friends encouraged him, and he submitted his work for publication in L'Illustration and Le Figaro.
Others were like simple folk songs, such as Carcassonne, which is the lament of a peasant who was never able to visit Carcassonne, a city on the Aude River near the Pyrenees, famous for its medieval fortress.
Although Nadaud wrote over 300 songs, he died in poverty.
A college in Wattrelos, in northern France, is named after him.
