August Buchner (2 November 1591 – 12 February 1661) was a German philologist, poet and literary scholar, an influential professor of poetry and rhetoric at the University of Wittenberg.

Before he achieved the magister degree, he was appointed professor of poetry in 1616[1] as the successor of Rodenberg by the court of Saxony.

Among his students are Simon Dach, Paul Fleming, Johann Franck, Paul Gerhardt, Christian Gueintz, Christian Keymann, Balthasar Kindermann, Johann Klaj, Martin Opitz, David Schirmer, Andreas Tscherning, Jakob Thomasius, Philipp von Zesen and Caspar Ziegler.

[3] Buchner's Hauptwerk, Anleitung zur deutschen Poeterei (Instructions for German poetry), was published in Wittenberg in 1665 after his death by his son-in-law Otto Praetorius [de].

[4] Buchner wrote the libretto for a ballet-opera Orpheus und Euridice with music by Heinrich Schütz, which was performed on 20 November 1638 for a courtly wedding.
