The Central Union of Stone Workers of Germany (German: Zentralverband der Steinarbeiter Deutschlands) was a trade union representing stone masons in Germany.
The union was founded in 1884 in Halle, as the Association of Stonemasons of Germany, as a purely professional organisation.
In 1903, it was centralised as the "Central Union of Stone Workers".
