Supernova 1604, also known as Kepler's Supernova or Kepler's Star, was a supernova in the Milky Way, in the constellation Ophiuchus. As of 2005, it is the last supernova to have been unquestionably observed in our own galaxy, occurring no greater than 6 kiloparsecs or about 20,000 light-years from Earth.

The supernova was first observed on October 9, 1604. The German astronomer Johannes Kepler first saw it on October 17, but he studied it so extensively that the supernova was subsequently named after him.

It was the second supernova to be observed in a generation (after SN 1572 seen by Tycho Brahe in Cassiopeia). No further supernovae have since been observed with certainty in the Milky Way, though many others outside our galaxy have been seen.
