Johann Hornung ( 1660 Tallinn – 1715) was a Baltic-German Lutheran clergyman and language enthusiast.
He worked as a sacristan in several Estonian churches, including Põltsamaa (1692-1698) and Karula (1698-1715).
With Adrian Virginius, he translated New Testament into North Estonian. 1694 he published religious book "Önsa Luterusse Laste Öppetuse ...", and he was a co-author of the religious book "Ma Kele Koddo ning Kirgo Ramatu".
His most important work was Latin-language Grammatica Esthonica ... which gave the overview of grammar of the North Estonian language.
