Günther Domenig (6 July 1934 – 15 June 2012) was an Austrian architect.Domenig was born in Klagenfurt, and studied architecture at the Graz University of Technology (1953–1959).
After working as an architectural assistant, he set up in practice with Eilfried Huth (1963–1973), producing buildings in a brutalist vein.
Domenig's first internationally acclaimed completed work was the Z-bank in Vienna, which signalled a much more expressionistic, counter-modernist aesthetic.
In addition to his practice, Domenig became a professor at the Graz University of Technology in 1980.
