Wiener Neudorf (Central Bavarian: Weana Neiduaf) is an Austrian town in the eastern part of the Mödling district, south of Vösendorf and Maria Enzersdorf, west of Biedermannsdorf, and north of Guntramsdorf.

By 1900 the telephone network was unified with the neighbouring municipalities and the sewage system had been extended.

Wiener Neudorf lies directly at the B-17 'Wiener Neudstädter Strasse', a major traffic route.

Due to the proximity of the Shopping City Süd, the road experiences frequent traffic jams.

Wiener Neudorf is home to the 'Industriezentrum NÖ Süd', a conglomerate of various industries and major economy factor in the south of Vienna.
