The Norwegian Central Union of Book Printers (, FFNB) was a trade union representing typographers and those in related trades in Norway.

The union was founded on 1 October 1882, the first trade union to be formed in Norway. It was initially named the Norwegian Central Travel Fund for Book Printers, but adopted its better-known name in 1885. In 1889, it led a lengthy strike in Oslo, after which it adopted the form of a modern trade union. It later affiliated to the Norwegian Confederation of Trade Unions.

The union had 7,440 members in 1924, but this then declined slightly, to 6,363 in 1963. In 1957, it renamed itself as the Norwegian Union of Typographers. In 1967, it merged with the Norwegian Lithographic and Chemographic Union and the Norwegian Union of Bookbinders and Cardboard Workers, to form the Norwegian Graphical Union.
