The Kepler Museum (Czech: Keplerovo muzeum) is a museum of astronomy in Prague, Czech Republic, named for the German astronomer Johannes Kepler.

It was founded in 2009, the International Year of Astronomy, with financial support from the Magistrate of the Capital City of Prague and Agentura ProVas, professional and organisational support from the Czech Astronomic Society and using premises owned by Jitka Steinwaldová.

The entrance tickets to the museum feature the astronomic dial of the Prague Astronomical Clock with the exact moment of entry to the museum, with the same data also expressed in the Old Bohemian and in the Babylonian manner.

The original entrance ticket was designed by Vojtěch Sedláček, CEO of Agentura ProVás.

The installation was transferred to the National Technical Museum and opened since spring of 2019.
