Herman Carl Mueller (1854 in Germany – September 22, 1941), was an American ceramicist.

The Westward Journey, one of Muellers earlier works, is a collection of limestone sculptures that form part of the Indiana Statehouse.

Mueller received the John Scott Award from the Franklin Institute of Philadelphia for "Process of and apparatus for manufacturing mosaics".

In 1878, Muller moved to Cincinnati Ohio where he worked as a sculptor.

After a few short business venture, Mueller was commissioned to create nine figures for the Indiana Statehouse.
