Nicolaas Grevinckhoven (Grevinchovius, Grevinghoven or Grevinchoven in German sources) (died 1632) was a Dutch Protestant minister, a combative proponent of the Remonstrant party.
In Rotterdam he was on bad terms with the Contra-Remonstrant minister Cornelis Geselius, who quarrelled insistently with Grevinckhoven at the prompting of the extremist Adriaan Smout. The result was an intervention of the magistrates, with the Contra-Remonstrants worshipping outside the town.[6] With Jacobus Taurinus of Utrecht he was one of the most strident of Remonstrant pamphleteers.[7]
In Antwerp after the Synod of Dort in 1619, he tried to rally the Remonstrants, who had suffered defeat at the Synod in theological terms, and had also lost a major political battle in Holland. He was one of those reshaping the movement into the Remonstrant Reformed Brotherhood,[8] in a committee with Johannes Wtenbogaert, Eduardus Poppius, Carolus Niellius and Johannes Arnoldi Corvinus.[9] While there he provided shelter for Hugo Grotius, recently escaped from imprisonment, in 1621.[10] Grevinckhoven spent time in Holstein.[8]
