Franz Chadbourne Eschweiler (September 6, 1863 – November 14, 1929) was an American lawyer and judge from Wisconsin.

He previously served five and a half years as a Wisconsin circuit court judge in Milwaukee County.

Rather than running for re-election in 1916, he ran for a seat on the Wisconsin Supreme Court, set to be vacated by the pending retirement of justice William H. Timlin.

Eschweiler won the spring 1916 election, and was appointed to begin his term early—in August 1916—following Timlin's death.

Eschweiler ultimately served on the Wisconsin Supreme Court until his own death in 1929.
