Carl Fredrich Baur (fl. c. 1850 - 1900)was a German map publisher active in Stuttgart during the mid to late 19th century. Baur was little known outside of Germany but nonetheless produced a number of important map most of which had a thematic or historic context. His most notable work is most likely the 1857 Atlas fur Handel und Industrie fur Kaufleute, Fabrikanten und Gewerbetreibende, one of the first industrial and commercial atlases of the 19th century.
