The Atlas Maior is the final version of Joan Blaeu's atlas, published in Amsterdam between 1662 and 1672, in Latin, French, Dutch, German and Spanish, containing 594 maps and around 3,000 pages of text. It was the largest and most expensive book published in the seventeenth century. Earlier, much smaller versions, titled Theatrum Orbis Terrarum, sive, Atlas Novus, were published from 1634 onwards. Like Abraham Ortelius's Theatrum Orbis Terrarum (1570), the Atlas Maior is widely considered a masterpiece of the Golden Age of Dutch/Netherlandish cartography.

Joan Blaeu was a Dutch cartographer born in Alkmaar, the son of cartographer Willem Blaeu.
