For the films of the same name, see Nanon (disambiguation).

559 Nanon is a minor planet orbiting the Sun. At the time of its discovery, Max Wolf was habitually naming asteroids after operatic heroines, suggesting is it most likely named after the lead character of Nanon, an 1877 opera by Richard Genée.
