Wolffs Telegraphisches Bureau (1849–1934) was founded by German Bernhard Wolff (1811–1879), editor of the Vossische Zeitung, and founder of the National Zeitung (1848-1938).
It was one of the first press agencies in Europe and one of the three major European telegraph monopolies until the World War II-era, along with the British Reuters and the French Havas. In 1865 they formed a European news cartel.
