Curt Wachsmuth (27 April 1837, Naumburg an der Saale – 8 June 1905, Leipzig) was a German historian and classical philologist. He was a son-in-law to philologist Friedrich Ritschl.
From 1856 to 1860 he studied at the universities of Jena and Bonn, where he later received his habilitation in classical philology and ancient history. In 1864 he became a professor in ancient history at the University of Marburg, followed by professorships in classical philology at the universities of Göttingen (1869–1877) and Heidelberg (1877–1885). From 1885 to 1905 he was a professor of classical philology and ancient history at the University of Leipzig. In 1897/98 he served as university rector.
Among his better written efforts were a two volume work on ancient Athens (1874, 1890), an introduction to the study of ancient history (1895) and with Otto Hense, a five volume edition of Stobaeus' Anthologium.
