The Lutheran Cathedral of Saint Mary (German: Evangelische Stadtpfarrkirche in Hermannstadt, Romanian: Biserica Evanghelică din Sibiu) is the most famous Gothic-style church in Sibiu (German: Hermannstadt), Transylvania, central Romania.

However, in the middle of the 16th century, it became a Lutheran parish, as Johannes Honter converted the Transylvanian Saxons to Protestantism.

This practice was banned in 1796 but one exception was made in 1803, when baron Samuel von Brukenthal was laid to rest in the crypt.

Originally, this instrument was built for the parish church in Boarta, and it was housed at the Samuel von Brukenthal National College until being moved to the Cathedral in 1948.

Also of interest is a large fresco, dating to 1445, which depicts scenes from the life, passion, and ascension of Jesus Christ.
