Teodor Janković Mirijevski (also written F. I. Mirievskii, Fedor Ivanovich Yankovich de Mirievo; Sremska Kamenica, 17 April 1741-Saint Petersburg, 22 May 1814) was a Serbian and Russian educational reformer, academic, scholar and pedagogical writer. For his accomplishments in educational reforms he was twice ennobled, by Maria Theresa in 1774 and by Catherine the Great in 1791. Among the great 18th century education reformers of Europe and Russia, Teodor Janković stands alone in that limelight. He became a member of the Russian Academy in 1783. He also held the rank of Brigadier in the Imperial Russian Army.
