Louis [or Ludwig] August Wollenweber (5 December 1807 – 25 July 1888) was a German-American German-language journalist and a writer of prose and poetry in Pennsylvania Dutch.

Upon the completion of his term of apprenticeship, he traveled through Germany as a journeyman worker, finally settling in Homburg and working for the Deutsche Tribüne.

He was compelled to emigrate to the United States, via France and the Netherlands, in consequence of his being one of the agitators of the "Hambacher Volksfest."

He later founded a new German-language paper, Der Freimuethige (The Free-Thinker), which lasted only for a short time.

In 1853 he sold the Demokrat to his brother-in-law, John S. Hoffman, and afterward resided in the Lebanon Valley and in Reading.
