Gerard van Rivieren, Latinized Gerardus Rivius (active 1592–1625) was a printer in the Southern Netherlands.
He was the publisher of Martin Delrio's famous witchcraft treatise Disquistiones Magicae and was at one time suspected of having printed Corona Regia, a satire on James I of England that caused diplomatic ructions.
[1] His printer's mark was a winged horse, and his motto "Totum sic irrigat orbem".
In 1598 he was using an Antwerp address, and from 1599 his shop was on the main market square in Leuven.
Of their children Johannes Rivius (1599–1665) became an Augustinian canon and a lecturer at Leuven University, while Petrus Rivius (1607–1666) became a Premonstratensian canon of Tongerlo Abbey.
