Frank Duveneck (October 9, 1848 - January 3, 1919) was an American figure and portrait painter.
Duveneck was born in Covington, Kentucky, the son of German immigrant Bernard Decker. Decker died when Frank was only a year old and his widow remarried Joseph Duveneck.
By the age of fifteen Frank had begun the study of art under the tutelage of a local painter, Johann Schmitt and had been apprenticed to a German firm of church decorators. While having grown up in Covington, Duveneck was a part of the German community in Cincinnati, Ohio, just across the Ohio River.
