Erwin Julius Ritter von Zach (18 April 1872 – 19 January 1942) was an Austrian diplomat and sinologist noted for his studies of Chinese literature and its translation, as well as his often harsh criticism of other scholars' work.
His German translation of the early Chinese anthology Selections of Refined Literature (Wen xuan ??) was the work's first complete translation in a Western language.
He was the second consul of the Austro-Hungarian concession of Tianjin.
