Master Francke O.P. (or Meister Francke, Frater Francke, respectively German for "Master Francke" and Latin for "Brother Francke") was a North German Gothic painter and Dominican friar, born ca. 1380 in the Lower Rhine region or possibly Zutphen in the Netherlands, who died ca. 1440, probably in Hamburg, where he was based at the end of his known career. He is called "Fratre Francone Zutphanico" ("Brother Frank of Zutphen") in one document. He may have trained as an illuminator and painter in France or the Netherlands, and later worked in Münster, before joining in St John's Priory in Hamburg by 1424 at the latest.
