Johannes van Keulen (1654, Deventer - 1715, Amsterdam) was a 17th-century Dutchcartographer. He published the influential nautical atlas the ''Zee-Atlas'' and the pilot guide ''Zee-Fakkel'' (meaning Sea-Torch in English).
In 1678 Johannes van Keulen established himself in Amsterdam and in 1680 he obtained a patent from the States of Holland and West Friesland allowing him to print and publish maritime atlases and shipping guides. These were books of maps and descriptions of itineraries, used by helmsmen for safe navigation. The patent was a kind of protection against illegal copying of produced books and charts. This was especially important for the atlases which were made with extensive initial costs. Van Keulen named his firm ‘In de Gekroonde Lootsman’ ('In the Crowned Pilot'). Soon Van Keulen struck a deal with cartographer Claes Jansz. Vooght.
From 1681 onwards the ''Nieuwe Lichtende Zee-Fakkel'' appeared, a five-volume atlas for which Vooght compiled the maps and which was illustrated by Jan Luyken. The five volume ''Zee-Fakkel'' made Johannes van Keulen famous. The ''Zee-Fakkel'' was published in 5 volumes between 1681 and 1684 containing over 130 new charts.
