Martin Hartmann (9 December 1851, Breslau – 5 December 1918, Berlin) was a German orientalist, who specialized in Islamic studies.
In 1875, he received his doctorate at the University of Leipzig as a student of Heinrich Leberecht Fleischer.
From 1876 to 1887 he served as a dragoman at the German General Consulate in Beirut.
From 1887 until his death in 1918 he taught classes at the Department of Oriental Languages in Berlin.As a professor in Berlin he strove hard for the recognition of Islamic studies as an independent discipline.
His numerous contributions to the field of Islamic studies were based on a sociological standpoint.
Many of these works were published in the journal "Die Welt des Islams" (The World of Islam), a publication of the "Deutsche Gesellschaft für Islamkunde", an organization that Hartmann was a co-founder of in 1912.
