Johann Friedrich Steinkopf (17 May 1771, Ludwigsburg - 4 April 1852, Stuttgart) was a German bookseller and publisher.
In 1840, the store and the publishing company were transferred to another nephew, Rudely Louis Hänel (1808–1847), who had been a partner since 1834.
One of his most notable publications was the Tägliche Hand-Buch in guten und bösen Tagen (Daily Handbook for Good and Bad Days) by Johann Friedrich Starck [de], the first completely new edition of that book since 1738.
His first original publication, the Ökonomische Handbuch für Frauenzimmer (Economic Handbook for Housewives, 1792), was coupled with a cookbook by Friederike Luise Löffler (1744-1805), and became a best seller, which is still being republished.
From 1836, they also published the youth-oriented magazine, Jugendblätter, for the pietist pastor, Christian Gottlob Barth.
