'''Theodosius Andreas Harnack''' ({{langx|ru|Феодосий Карлович Гарнак|translit=Feodosij Karlovič Garnak}}; {{osd|3 January|1817|22 December 1816}}, [[St. Petersburg]] – {{osd|23 September|1889|11}}, [[Dorpat]] (now {{lang|et|Tartu}})) was a [[Baltic German]] [[theology|theologian]].

A professor of [[Divinity]], he started his career as a [[Privatdozent]] for [[church history]] and [[homiletics]] at the [[Imperial University of Dorpat]] (in what is today Tartu, [[Estonia]]) in 1843, he was further appointed university preacher in 1847. Since 1848 he held an ordinary chair (tenure) as professor for [[practical theology|practical]] and [[systematic theology]]. Between 1853 and 1866 Harnack was professor at Frederick Alexander University (merged in the [[University of Erlangen-Nuremberg]] since 1961) in [[Erlangen]], Bavaria, [[German Confederation]] (now Germany).

Harnack was a staunch [[Lutheran]] and a prolific writer on theological subjects; his chief field of work was practical theology, and his important book on that subject summing up his long experience and teaching appeared at Erlangen (1877–1878, 2 vols.). The [[liturgy]] of the then [[Lutheran church]] in [[Russia]] has, since 1898, been based on his ''Liturgische Formulare'' (1872).

His twin sons were the German [[theology|theologian]] [[Adolf von Harnack]] (1851–1930) and [[mathematician]] [[Carl Gustav Axel Harnack]] (1851–1888). His other two sons were also successful scientists, with the pharmacology and physiological chemistry professor [[Erich Harnack]] (1853–1914) and the history of literature professor [[Otto Harnack]] (1857–1914), father of [[Arvid Harnack]] and [[Falk Harnack]].
