The church's organ was finished in 1553 by Hendrik Niehoff and Jasper Johansen and rebuilt in 1714 by Arp Schnitger student, Matthias Dropa and in the later 20th century by Rudolf von Beckerath.
Among its noted organists were Christian Flor (1676–1697) and Georg Böhm (1698–1733).

As a young man, Johann Sebastian Bach was resident (1700–1702) at a school attached to the nearby Michaeliskirche, where he appears to have been a kind of organ scholar.
Documentary evidence suggests, in the opinion of Bach scholar Christoph Wolff, that Böhm gave Bach organ lessons at St. Johannis.

The organ has been featured on BBC television in several programmes of "21st century Bach", a project in which John Scott Whiteley plays historic organs.
