Johannes de Laet (1581-1649) was a Flemish-Dutch mapmaker. He was born in Antwerp but raised in Amsterdam as a Protestant fleeing Spanish-Catholic persecution. In 1620, he became one of the founders of the Dutch West India Company and served as its first director from its creation until his death in 1649.

As a mapmaker, De Laet worked closely with Hessel Gerritz, the chief cartographer for the Dutch East India Company. He was a respected publisher and intellectual, and in 1618, the city of Leiden sent him as an elder delegate to the Synod of Dort.
