Caspar Friedrich Hachenberg (14 December 1709 (baptised) – 1 April 1793), was rector of the Latin school of Wageningen, The Netherlands (1740–1789) and writer of Greek and Latin grammars.
Hachenberg was born in 1709 at Neuwied, the son of the town secretary Friedrich Wilhelm Hachenburg and Charlotte Albertine Bachoven. He studied theology at the university of Marburg and the Gymnasium Illustre of Bremen, and started his working career in Jemgum in East Friesland, Germany, probably as a reformed parson.
