Benno Erdmann (30 May 1851, Guhrau - 7 January 1921, Berlin) was a German neo-Kantian philosopher, logician, psychologist and scholar of Immanuel Kant.
Erdmann received his Ph.D. in 1873 from the University of Berlin with a dissertation on Kant. The title of his thesis was Die Stellung des Dinges an sich in Kants Aesthetik und Analytik. Hermann von Helmholtz proposed Erdmann's publication Die Axiome der Geometrie (1877) as the basis for a habilitation. In 1878 he became an associate professor at the University of Berlin, in 1879 a full professor at the University of Kiel, and in 1884 he went to the University of Breslau, in 1890 to the University of Halle, in 1898 to the University of Bonn and in 1909 he returned to Berlin.
He was the father of journalist Lothar Erdmann.
