Eugen Napoleon Neureuther (13 January 1806 – 23 March 1882) was a German painter, etcher, and illustrator.
Born in Munich, Germany, he was the son and pupil of the painter Ludwig Neureuther (1775–1830).
His illustrations for Goethe's romances and ballads with marginal drawings, published in 1829–39, made his reputation.
In 1830 Neureuther visited Paris, where his illustrations of the scenes of the July revolution appeared under the title Souvenir du 27, 28, 29 juillet (1831).
After his return he published Marginal Drawings to Bavarian Poets (1832–35), and in 1838 completed his illustrations to Herder's Cid.
