Johann Balthasar Neumann (January 27, 1687 - August 19, 1753) was a German Baroque architect who designed the Vierzehnheiligen and several churches in Würzburg.

Neumann was born in Cheb (Eger), Bohemia. He moved to Würzburg in 1711 and became a patron of the Schonborn family in 1717. In Würzburg he built the Residenz, residential palace of the Schonborn prince-bishop of Würzburg. He died in Würzburg, Germany.

A picture of him could be seen on the former 50-DM note together with the famous staircase located in the Residenz of Würzburg.
