F. W. Kähler (fl. c. 1863 - 1907) was a German lithographer active in Hamburg in the late 19th and early 20th centuries. Kähler began printing around 1863 under the imprint of 'Lithographische Anstalt F. W. Kähler'. Much of his work is realated to promoting the robust Hamburg shipping industry. Around 1901, the firm began trading as F. W. Kähler Erben, having passed to his heirs, W. Kähler, H. Kähler, E. Kähler, and M. Kähler.
