Vladan Đorđević (b. 21 Nov. Jul. / 3 Dec. 1844greg. in Belgrade; † 18 Aug. 1930 in Baden near Vienna) was a Serbian physician, author, and politician. In 1897-1900 he was prime minister of his country.
From 1864 he studied medicine at the University of Vienna, where he received his doctorate in 1869 and trained as a surgeon for the next two years. Returning to Serbia in 1871, Đorđević became a military surgeon and chief of the surgical department at the Belgrade Military Hospital. A year later he founded the Association of Serbian Physicians, in 1873 he became personal physician to Prince Milan Obrenović. In 1876 he was one of the co-founders of the Serbian Red Cross. Since 1877, he was the commander-in-chief of the entire medical service of the Serbian Army. In this capacity, Đorđević initiated far-reaching reforms of medical care in the army after the war.
