The Harmonia Macrocosmica is a star atlas written by Andreas Cellarius and published in 1660 by Johannes Janssonius.

The first part of the atlas contains copper plate prints depicting the world systems of Claudius Ptolemy, Nicolaus Copernicus, and Tycho Brahe.

At the end are star maps of the classical and further constellations, the latter ones as introduced by Julius Schiller in his Coelum stellatum christianum of 1627.

In the foreword to his Chronologica, Gerard Mercator stated the intention to publish an atlas which would cover everything of the then-known cosmos, geography and history of the earth.

He and fellow-cartographer Hendricus Hondius published their Novus Atlas in 1636, which featured over 320 maps in four languages.
