Pieter van den Keere (1571 - c. 1646) was a Dutch engraver and cartographer active in London and Amsterdam in the late 16th and early 17th centuries. Keere, who is alternatively known as Kaerius or Coerius, was born in Gent, the son of printer and type founder Hendric van den Keere. Religious persecution in the Low Countries forced Keere, with many others, to take refuge in London, where they established themselves. There Keere married the sister of Jodocus Hondius, also a refugee in London, and it was most likely through Jodocus that he mastered engraving and mapmaking. Keere is responsible for numerous maps, most of which are associated with the Hondius firm. Some of his most notable works include numerous county maps of the British Isles that were later compiled into Camden's Britannia. Keere also engraved many of the maps included in the Jansson Atlas Minor.
