Hermann Groeber was a German painter who was known throughout Germany as a portraitist and landscape artist.

Hermann Groeber gained early success as a self-employed painter. He joined the German Association of Artists, and after Ludwig Schmid-Reutte was appointed to Karlsruhe, Groeber took over his class of nude acts, which soon enjoyed great popularity. In 1907 he became head of the nude class at the Munich Academy and was appointed full professor there in 1911.

In 1911 he received the Golden Medal in the exhibition in the Munich Glass Palace.
