The Café Zimmermann, or Zimmermannsche Kaffeehaus was the coffeehouse of Gottfried Zimmermann in Leipzig which from 1720 hosted the Collegium Musicum founded by Georg Philipp Telemann as a law student in 1702 and later directed by Johann Sebastian Bach between 1729 and 1739 which formed the backdrop to the first performances of many of Bach's secular cantatas, e.g. the Coffee Cantata, and instrumental works. In 1723 it was largest and best-appointed Kaffeehaus of Leipzig and a centre for the middle classes and gentlemen. The location was south of the Brühl, north of the Marktplatz in the Katharinenstraße, then the most elegant street of Leipzig. The name of the street had been taken from the old St. Catherine's Chapel which had been demolished in 1544. In Telemann's and Bach's day only the name of the street remained.
Zimmermann charged the Collegium Musicum no fee for hosting their concerts, nor were the audience charged a fee; Zimmermann's expenses were repaid by sales of coffee. The concerts ended with Zimmermann's death in 1741. The building was destroyed during an air raid on Leipzig in December 1943.
The coffeehouse was located at Katharinenstrasse 14, a four-and-a-half storey Baroque building constructed by Doering around 1715. It consisted of two adjoining rooms,one approximately 8 x 10 metres, the other approximately 5.5 x 10 metres. 
A French classical music ensemble named Café Zimmermann is named after this coffeehouse.

The Collegium Musicum was one of a number of concert series in Leipzig, a city with a large music-loving [population]."

Die Zuhörer bezahlten keinen Eintritt, sie tranken dafür Kaffee."
