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.
The former building was built in 1507. After the Reformation, it was used as a Lutheran church until 1539, and again from 1712 to 1885. It was demolished in 1886. With 87 metres it is Leipzig's tallest church.
