Karl Raupp (born 2 March 1837 in Darmstadt; died 14 June 1918 in Munich) was a German landscape and genre painter.
After studying genre painting under Jakob Becker at the Städel Institute in Frankfurt, he became a pupil and zealous follower of Piloty in Munich (1860–65), where he soon gathered a small school. After 1865, he opened a studio, taking private pupils in painting. In 1868 his reputation as a teacher gained for him the position of professor in the art school at Nuremberg, where he stayed until 1879, when he returned to his former residence to become professor at the art academy in Munich.
His finely colored scenes from fishermen's and peasant life around Chiem Lake, which form his favorite subjects, show equal devotedness in the treatment of landscape and figures, and include:
He published a Katechismus der Malerei (Painting catechism; 3d ed. 1898).
