Friedrich Kluge (21 June 1856 – 21 May 1926) was a German philologist and educator. He is known for the Etymological Dictionary of the German Language (Etymologisches Wörterbuch der deutschen Sprache), which was first published in 1883.^[1]

Kluge was born in Cologne. He studied comparative linguistics and classical and modern philologies at the universities of Leipzig, Strasbourg and Freiburg. As a student, his instructors were August Leskien, Georg Curtius, Friedrich Zarncke and Rudolf Hildebrand at Leipzig and Heinrich Hübschmann, Bernhard ten Brink and Erich Schmidt at the University of Strasbourg.^[2]

He became a teacher of English and German philology at Strassburg (1880), an assistant professor of German at the University of Jena in 1884, a full professor in 1886, and in 1893 was appointed professor of German language and literature at Freiburg as a successor to Hermann Paul.^[2]

A Proto-Germanic sound law that he formulated in a paper in 1884^[3] is now known as Kluge's law.

He died in Freiburg, Germany.
