Philipp Clüver (1580 – 31 December 1622) was an Early Modern German geographer and historian.

Clüver was also a prolific writer on mathematical and theological subjects. He is remembered by collectors and historians of cartography for his edition of Ptolemy's Geographia (based on Mercator's edition of 1578) and for miniature atlases that were reprinted for most of the 17th century. Many of his maps were etched for him by Petrus Bertius.
