Matthaeus Stach (sometimes anglicized to Matthew Stach) (March 4, 1711 - December 21, 1787) was a Moravian missionary in Greenland. Matthäus Stach was born in Mankendorf (Czech: Mankovice) near Zauchtenthal in Moravia. He was home schooled since his parents did not want to send the family to attend the Roman Catholic schools. In 1728, he arrived at the Moravian community of Herrnhut in Saxony. In 1733, Stach traveled to Greenland together with Christian David and his cousin Christian Stach where they were greeted by the Danish pioneer missionary Hans Egede. Together they founded the settlements of New Herrnhut (modern Nuuk) and Lichtenfels. In 1741, he made a return trip to Germany where he was both ordained into the ministry and became married.
