Café Griensteidl was a traditional Viennese café located at Michaelerplatz 2 across from St. Michael's Church and St. Michael's Gate at the Hofburg Palace in the Innere Stadt first district of Vienna, Austria. The café was founded in 1847 by former pharmacist Heinrich Griensteidl. In January 1897, the original building was demolished during the course of the renovation of Michaelerplatz. During the early twentieth century, the café was frequented by many artists, musicians, and writers, including Hugo von Hofmannsthal, Arthur Schnitzler, Arnold Schoenberg, Alexander Zemlinsky, Hermann Bahr, Friedrich Eckstein, Rudolf Steiner, Hugo Wolf, and Stefan Zweig.
In 1990, the café was reopened and became a popular location among the Viennese coffeehouse culture. As they could not afford the rising rents anymore, Griensteidl closed in June 2017.
