كارل يوهان فرويدنبرگ (Karl Johann Freudenberg ؛ ForMemRS[1] (29 يناير 1886 ڤاينهايم، بادن – 3 أبريل 1983 ڤاينهايم) كان كيميائياً ألمانياً who did early seminal work on the absolute configurations to carbohydrates, terpenes, and steroids, and on the structure of cellulose (first correct formula published, 1928) and other polysaccharides, and on the nature, structure, and biosynthesis of lignin. The Research Institute for the Chemistry of Wood and Polysaccharides at the University of Heidelberg was created for him in the mid to late 1930s, and he led this until 1969.[2]

درس فرويدنبرگ في جامعة بون في 1904، وجامعة برلين من 1907 حتى 1910، where he studied with Emil Fischer.
