Johann Friedrich Judeich (27 January 1828, Dresden – 28 March 1894, Tharandt) was a German forester.
He studied forestry at the Royal Saxon Academy of Forestry in Tharandt and economics in Leipzig, where he was a pupil of Wilhelm Roscher. From 1849 to 1857, he was associated with the Saxon Forstvermessungs-Anstalt (surveying institute), followed by work as a forestry director in the employ of Count Morzin.
In 1862 he became part of the Böhmischen Forstschulverein (Bohemian Forestry School Association) in Weißwasser, and in 1866 returned to Tharandt as director of the Academy of Forestry, succeeding Carl Heinrich Edmund von Berg (1800–1874). Here he remained as director until his death in 1894.
He was the author of Die Forsteinrichtung, a highly regarded work on forest management, first published in 1871 and subsequently issued over several editions. The following are some of the published works associated with Judeich:
- Tharander forstliches Jahrbuch, 1884 – Tharandt forestry yearbook.
