Franz Michael Leuchsenring (13 April 1746 – February 1827) was a German writer of the German Enlightenment.
In 1769, Leuchsenring with Friedrich Heinrich Jacobi, Johann Gottfried Herder, and Johann Wolfgang Goethe were known as members of the Merckschen Circle in Darmstadt. Almost all his circle broke with Leuchsenring, however, because they did not trust him. After moving to Berlin, he was briefly teacher of philosophy to Crown Prince Frederick William III of Prussia. Along with bookseller and author Christoph Friedrich Nicolai, Royal librarian Johann Erich Biester, and Moses Mendelssohn, the German Jewish philosopher, he became a member of the Berlin Wednesday Society. Later, he went to Paris, where he lived as a Jacobin and there died.
