Friedrich Karl Forberg (30 August 1770, Meuselwitz – 1 January 1848, Hildburghausen) was a German philosopher and classical scholar.
He studied under Karl Leonhard Reinhold at Jena. In 1791 he travelled to Klagenfurt, writing to Reinhold that there was much sympathy for the French Revolution, and to the followers of Immanuel Kant that the young ladies of Klagenfurt substituted Kant’s writings (modestly bound in black) for their prayer books.
