Erwin Pröll (born 24 December 1946) is an Austrian politician of the Austrian People's Party (ÖVP). Since 22 October 1992 he has been governor (Landeshauptmann) of Lower Austria. He is the longest-serving governor in Austria.
He was born in Radlbrunn, Lower Austria and after obtaining his Matura at Tulln he studied at the University of Natural Resources (BOKU), Vienna.
The transfer of the regional administration from Vienna to Sankt Pölten took place during his administration.
Pröll is seen as a supporter of a Grand Coalition between the ÖVP and Social Democratic Party (SPÖ). In the year 2000 he was still a supporter of the "black-blue" coalition (ÖVP with the Freedom Party (FPÖ)), but two years later argued against such an arrangement. Pröll also has a good relationship with Viennese mayor Michael Häupl (SPÖ).
Great interest was aroused in Europe when he proposed a tax on mobile phone masts in the state of Lower Austria. Together with the SPÖ he suggested legally regulating mobile phone transmitters, with the aim of reducing the overall number. At the same time the state planned to set up a local telecommunications infrastructure by means of a Wireless LAN.
After an agreement with the mobile radio companies, the taxation was not realized. The agreement in fact was used as an example for other regions.
In 2006 he hosted a conference with EU politicians over subsidiarity in Sankt Pölten.
Pröll is married with four children. He is the uncle of Josef Pröll, former Austrian Vice Chancellor and Minister of Finance.
The magazine Falter in 2002 reported the response by regional party secretary Ernst Strasser to criticism of Pröll's confession that he had only ever managed to finish one book, Karl May's cowboy novel Der Schatz im Silbersee (The Treasure of Silver Lake): "People like that, at least it shows the governor isn't a know-all."
