Traiskirchen is a city and Municipality in the district of Baden in Lower Austria in Austria. It is 20 km south of Vienna, in the Thermenlinie region, known for its wine and heurigers. Traiskirchen is home to the Traiskirchen Lions basketball team. The town has the oldest public astronomical observatory in Lower Austria. The city is also known for its refugee camp the "Bundesbetreuungsstelle für Asylwerber".

In eastern Austria, a Heuriger is a tavern where local winemakers serve their new wine under a special licence in alternating months during the growing season. Each state in Austria has slightly varying rules on how many Heuriger of a town can be open at any given time and for how long in total during the year. The Heurige are renowned for their atmosphere of Gemütlichkeit shared among a throng enjoying young wine, simple food, and – in some places – Schrammelmusik. They correspond to the Straußwirtschaften in the German Rheinland, the Frasche in Friuli-Venezia Giulia, and Osmica in Slovenia.
