Johann Franz Adolph Hoffmann (23 March 1858 – 1 December 1930) was a German socialist politician and Prussian Minister for Science, Culture and Education.
He joined the Social Democratic Party of Germany, and from 1890 was the editor of local socialist newspapers, then in 1893 became a book dealer and publisher.
He was known for his opposition to the ways in which Christianity was practiced by the wealthy and his advocacy for a radial separation of church and state, for this he was nicknamed "Ten Commandments Hoffmann" as a result.
During the November Revolution, Hoffmann together with Konrad Haenisch became Prussian Minister of Science, Art and Popular Education for a few months.
His strongly anticlerical remarks he made in office helped mobilize the Catholic electorate, who feared a new Kulturkampf.
