Franz Felix Adalbert Kuhn (19 November 1812 – 5 May 1881) was a German philologist and folklorist.

[1] But it is on Kuhn's researches into the language and history of the Indo-Germanic peoples as a whole that his reputation is founded.

His chief works in this connection are Zur ältesten Geschichte der Indogermanischen Völker (1845), in which he endeavoured to give an account of the earliest civilization of the Indo-Germanic peoples before their separation into different families, by comparing and analysing the original meaning of the words and stems common to the different languages; Die Herabkunft des Feuers und des Göttertranks (1859; new edition by Ernst Kuhn, under title of Mythologische Studien, 1886); and Über Entwicklungsstufen der Mythenbildung (1873), in which he maintained that the origin of myths was to be looked for in the domain of language, and that their most essential factors were polysemy and homonymy.

Kuhn was also the editor of the Zeitschrift für vergleichende Sprachforschung auf dem Gebiete der Indogermanischen Sprachen, which was at his time the standard periodical on the subject.
