Karl Franz Otto Dziatzko (27 January 1842 – 13 January 1903, Göttingen) was a German librarian and scholar, born in Neustadt, Silesia.

From 1859 to 1863 he studied classical philology at the universities of Breslau and Bonn. At Bonn, he was influenced by philologist Friedrich Wilhelm Ritschl and worked as an assistant at the university library.

In 1871 he became head librarian at the University of Freiburg, where he also obtained his habilitation the same year. After a brief stint as a schoolteacher in Karlsruhe, he was appointed director of the university library at Breslau (1872).
