Conrad Cichorius (25 May 1863 in Leipzig – 20 January 1932 in Bonn) was a German historian and classical philologist. He is known for publishing a complete survey of the reliefs of Trajan's Column, which still forms the basis of modern scholarship.^[1]

From 1882 to 1886 he studied at the universities of Freiburg, Leipzig and Berlin, and in 1895 became an associate professor at Leipzig. Later on, he was a full professor of ancient history at the universities of Breslau (1900–16) and Bonn (1916–28). In 1923/24 he served as university rector.^[2] His doctoral students included Vasile Pârvan.
