Louis Lang (29 February 1812 – 6 May 1893) was a German-American painter.

His father, a historical painter, wished him to become a musician, but his taste was for art. At the age of 16, he executed pastels with success. He studied at Stuttgart and Paris, and settled in the United States in 1838, his studio being for several years in Philadelphia.
