Rudolf Koch (November 20, 1876 - April 9, 1934) was a leading German calligrapher, typographic artist and teacher, born in Nuremberg. He was primarily a calligrapher with the Gebr. Klingspor foundry. He created several fonts, both in fraktur and normal formats. Fritz Kredel studied under Koch.

Koch wrote a book of 493 old-world symbols, monograms and runes entitled The Book of Signs which was published in 1955 by Dover Publications, INC. and which belongs to the Dover Pictorial Archive Series.
