The Austrian Construction Union (German: Österreichische Baugewerkschaft) was a trade union representing building workers in Austria.
The union was founded in 1916 as the Central Association of Construction Workers, when the Central Union of Austrian Builders merged with the Austrian Association of Builders' Labourers.
It later absorbed the Austrian Union of Chimney Sweeps, and part of the Austrian Union of Glass Workers.
From 1928, it was affiliated to the new Federation of Free Trade Unions in Austria.
[1] From 1929, the union was led by president Johann Böhm.
