St. Hyacinth's Church is a Gothic building, formerly a church, in Vyborg, Leningrad Oblast, Russia.
It was built in the sixteenth century as a private church for members of the nobility, and it became a Roman Catholic church, dedicated to Saint Hyacinth, in 1802.
In 1970, the neglected and disused building was restored for use as a children's art school.
The wrought iron railings here once belonged to Vyborg Cathedral.
