Julius Hugo Bergmann was a German painter.
Bergmann attended the Städelsche Institut in Frankfurt am Main in 1879, where he became a pupil of Heinrich Hasselhorst. From 1883 to 1888 he was a pupil of Gustav Schönleber and Hermann Baisch at the Karlsruhe Academy of Art. He then undertook study trips to Hungary, Holland, northern Scotland and the Upper Rhine.

He taught animal and landscape painting at the Düsseldorf Art Academy from 1897 to 1903 and animal painting at the Karlsruhe Art Academy from 1905 to 1919. Julius Bergmann was involved in the founding of the Karlsruhe Artists' Association and founder of the Strasbourg Artists' Association in Ruprechtsau. He belonged to the Munich Secession, was a founding member of the Düsseldorf Artists' Association in 1899 and an early member of the German Artists' Association, where his name can be found in the list of members as early as 1906.

Bergmann's motifs were primarily animals and landscapes with staffages of people, including from the Old Rhine near Karlsruhe and from studies he brought back from his travels. He showed his work in numerous national and international exhibitions. At the art exhibition at the Crystal Palace in Sydenham, London, in 1887, he was awarded a bronze medal. On the occasion of his 60th birthday, a special exhibition of his works was held at the Kunstverein Karlsruhe in 1921.
