Eugen Wüster (10 October 1898 – 29 March 1977) was an industrialist and terminologist, regarded as "the father of technological standardization".

Wüster coined many of the international principles of terminology standardization and contributed to the foundations of the modern information society.

The Eugen-Wüster Archives at the University of Vienna as well as at the Esperanto Museum and Department of Planned Languages of the Austrian National Library are based on material that he bequeathed.
