Friedrich Staub (30 March 1826 – 3 August 1896) was a Swiss lexicographer, dialectologist and librarian.

From 1850 to 1858 he was in charge of a private school in his hometown of Männedorf, and afterwards spent several years as a private tutor in Zürich.

He was a catalyst in the creation of the Schweizerische Nationalbibliothek (Swiss National Library).

[1][2] From 1862 he headed the Verein für das Schweizerdeutsche Wörterbuch (Association for the Swiss-German Dictionary) and up until 1896 was editor-in-chief of the Schweizerisches Idiotikon ("Swiss idioticon", a dictionary of the Swiss-German language).

[3] In 1874 he published a treatise on the vocalization of the consonant "n" in Swiss Alemannic ("Staub's law"), titled Die Vokalisierung des N bei den schweizerischen Alemannen.
