Johann Georg Seidenbusch (5 April 1641 – 10 December 1729) was a Bavarian priest, painter, and composer, an influential figure in the religious landscape of the Baroque period. His life's work was in the creation of the oratory of Aufhausen Priory, of which he was the first Provost.
In 2015, Seidenbusch was declared to be a Servant of God, a step towards canonization.
