Fritz Friedrichs (17 May 1882, Hamburg - 28 July 1928, Hoopte, Harburg District) was a German Post-Impressionist painter.
After completing his primary education in 1898, he enrolled at the Kunstgewerbeschule in Hamburg and, two years later, became a student of Arthur Siebelist.
In 1904, he and his fellow students held a major exhibition at the Galerie Commeter [de], a highly respected gallery that had been established in 1821.
After spending some time in a military hospital, he was discharged and went back to exhibiting, notably with the Free Secession in 1919.
A major retrospective of his work, "Die Siebelistschüler Fritz Friedrichs und Walter Voltmer" was presented by the Hamburgische Landesbank in 1991.
