Old St. Peter's Church is a Lutheran parish and church in the old town of Leipzig, Germany. The present church building, in Gothic Revival style, was erected from 1882 onwards at the Gaudigplatz, and also serves as a concert venue. It replaced a former building at a different location.

Petersstrasse is one of the oldest streets in Leipzig's district of Mitte. For centuries it was a main and commercial street for the Leipzig trade fair with exhibition houses, inns and shops. In the second half of the 19th century, many of the old buildings on the street fell victim to the modernization of the city center. Today it is a heavily frequented pedestrian zone in a prime location with shopping centers, department stores, shops, restaurants and cinemas.
