Fritz Helmuth Ehmcke (1878–1965) was a German graphical designer, typographer and illustrator.
Born in Inowrocław, Prussia (now Poland), Ehmcke was educated as a lithographer in Berlin during 1893–1897. In 1900, he was a co-founder of Steglitzer Werkstatt. From 1903, he taught at the Kunstgewerbeschule in Düsseldorf, from 1913 to 1938 in Munich, during 1920-1921 also in Zürich. During 1946 to 1948, he was professor at the Academy of Fine Arts, Munich.
He designed a number of typesets, notably Ehmcke-Antiqua and Ehmcke-Kursiv in 1909/10 (adopted for English-language typesetting by Stephenson Blake under the name Carlton).
