Adolph Friedländer (17 April 1851 – 7 July 1904) was a famed German lithographer of posters and a publisher hailing from Hamburg.

First learning lithography at his father's shop in Hamburg, he received formal training in Berlin and returned to operate independently in 1872.

The business suffered greatly when World War I broke out because the entertainment industry, the printshop's lifeblood, came to a virtual standstill.

After the Nazi regime came into power in 1933, the business, run by a Jewish family but a "Devisenbringer,"—a company that brought in foreign currency—was allowed to continue for a few more years but was finally shut down.

Friedländer breakthrough moment came when he received large orders of posters advertising Carl Hagenbeck's animal shows in 1883 and 1884.

Print volume rose in the 1920s, but then fell off sharply to a level of about 100 poster designs per year as a result of the Great Depression.

In addition to working at the family business, Otto Max also managed the Flora Theater until 1934, at which time he traveled with the Sarrasani circus to South America.

Ludwig transitioned the company to use of modern offset printing, working with chief draftsman Wilhelm Eigener (1904–1982) who specialized in wildlife illustration.

The traditional printer's mark of the company was a heart-shaped leaf with serrated edges, sometimes called a "Judenkirsche" ("Jews cherry").

Friedländer's press employed specialist artists for different types of posters, including Christian Bettels, considered one of the best animal draftsmen of his time.

In 2002, Stephan Oettermann and Jan J. Seffinga created an index of Friedländer posters containing detailed descriptions of the works and an extensive bibliography; in 2004 a fourth revised edition was issued.
