Café Schwarzenberg is a traditional Viennese coffee house, located on the Ringstraße boulevard (Kärntner Ring No. 17) near Schwarzenbergplatz in the central Innere Stadt district of Vienna, Austria. Unlike many other traditional Viennese coffeehouses, the Cafe Schwarzenberg did not cater to a clientele of artists and intellectuals. The interior is notable for having remained largely unchanged since it was opened in the 19th century.
