Georg Ludwig Walch (8 May 1785, Jena – 21 January 1838, Greifswald) was a German classical philologist largely known for his edition and analysis of works by the Roman historian Tacitus. He was the grandson of theologian Johann Georg Walch (1693–1775).
Beginning in 1805, he studied at the University of Jena, where he subsequently worked as a librarian. In 1808 he obtained his habilitation at Jena. Since 1811 he served as an instructor of Latin and Greek languages at the Grauen Kloster in Berlin. In 1830 he succeeded Christian Wilhelm Ahlwardt as a professor of ancient languages at the University of Greifswald.
