Johann Friedrich Wilhelm Wolff, nicknamed "Lupus" (21 June 1809 – 9 May 1864) was a German schoolmaster, political activist and publicist.

Wolff was born in Tarnau, a village in the Schweidnitz district of Silesia, Prussia (now Tarnawa [pl], Lower Silesian Voivodeship, Gmina Żarów, Poland).

[1] In 1831 he became a member of a radical students' association, for which he was imprisoned between 1834 and 1838 (mainly in Fort Srebrna Góra), following the resumption of persecution of these types of organisations by the Bundestag, in line with the Carlsbad Decrees.

There, he attempted to become a private tutor, having been legally excluded from public teaching due to the interruption of his studies by his arrest.

He served as an editor of the Neue Rheinische Zeitung newspaper in 1848-1849, and as a member of the Frankfurt National Assembly.
