Johann Kaspar Zeuss (or Zeuß, 22 July 1806 – 10 November 1856) was a German historian and founder of Celtic philology. He is credited with demonstrating that the Celtic languages belong to the Indo-European group.

Zeuss was born in Kronach, Upper Franconia, and studied at the gymnasium of Bamberg. His parents wished him to enter the priesthood, but he chose a scholarly career, inclining particularly to historical and linguistic studies. He entered the University of Munich and after graduating, taught at the gymnasium there. In 1837 his book Die Herkunft der Baiern von den Markomannen (The Descent of the Bavarians from the Markomans), which brought him an honorary PhD from the University of Erlangen. The same year he went to Speyer to teach history at the lyceum and remained there until 1847, when he accepted a professorship of history at the University of Munich. This he resigned on account of poor health and was transferred to the lyceum in Bamberg. In 1853 there appeared his monumental Grammatica Celtica, which brought him fame. Two years after he took leave of absence to recover his health, but he died in Kronach the following year.

Zeuss was a scholar of great erudition, combining a knowledge of philology with history and ethnology. His Germanic studies had taught him the necessity of knowing Celtic languages, and he went to work to investigate this neglected field. To get at the sources, the old manuscripts, particularly those in Old Irish, he journeyed to Karlsruhe, Würzburg, St. Gallen, Milan, London, and Oxford, and everywhere made extracts or copies. Both ancient and modern dialects received his attention. His Grammatica Celtica proved beyond doubt that the Celtic languages were a group of the Indo-European family, which put Celtic philology on a sound scientific basis. After the author's death the work was revised and re-edited by Hermann Ebel (Berlin, 1871). Other works by Zeuss are Traditiones possessionesque Wirzenburgenses (1842) and Die Freie Reichstadt Speyer vor ihrer Zerstörung (The Free Imperial City of Speyer before its Destruction).
