The Warwick Furnace Farms is a historic district that is located in northern Chester County, Pennsylvania, United States that includes the ruins of an early iron furnace that was owned by Anna Rutter Nutt, widow of Samuel Nutt.

The furnace operated through the 1860s and supplied the iron used in the iron-clad ship the USS Monitor during the Civil War.
