Bavaria-Munich (Middle High German: Baiern-Münichen) was a duchy that was a constituent state of the Holy Roman Empire from 1392 to 1505.

After the death of Stephen II in 1375, his sons Stephen III, Frederick, and John II jointly ruled Bavaria-Landshut.

After seventeen years, the brothers decided to formally divide their inheritance.

In 1429 portions of Bavaria-Straubing including the city of Straubing were united with Bavaria-Munich.

The duchy existed for a little more than a hundred years before Bavaria was reunited under Albert IV, Duke of Bavaria.
