Eugène Ketterer (7 July 1831 – 18 December 1870) was a prolific French composer and pianist who was known for his numerous salon arrangements of contemporary opera arias. Born in Rouen, France, of an originally Alsatian family, Ketterer became a student at the Paris Conservatoire in his early youth, where he studied with Antoine François Marmontel. He won second prize for solfège in 1847 and a premier accessit in 1852. After his graduation until his death in Paris in 1870, he appeared constantly as a pianist winning wide repute for his fantasies and drawing-room pieces, of which he wrote a large number, but only a few of which are still in the repertoire.
