The Landtag of Bavaria, officially known in English as the Bavarian State Parliament, is the unicameral legislature of the German state of Bavaria. The parliament meets in the Maximilianeum in Munich.

The Christian Social Union in Bavaria is a Christian democratic and conservative political party in Germany. Having a regionalist identity, the CSU operates only in Bavaria while its larger counterpart, the Christian Democratic Union (CDU), operates in the other fifteen states of Germany. It differs from the CDU by being somewhat more conservative in social matters, following Catholic social teaching. The CSU is considered the de facto successor of the Weimar-era Catholic Bavarian People's Party.
