Enfield Falls Mill and Miller's House, also known as Treman House and Mill, is a historic grist mill and former millowner's residence located at Robert H. Treman State Park near Ithaca in Tompkins County, New York. The mill is a 2 1/2-story frame structure over a stone foundation. It is a turbine-powered mill constructed in 1839. The mill has three runs of stones: one for griding buckwheat, one for grinding wheat, and a third for grinding coarser grain. The mill ceased operation in 1917. The millowner's house is a simple but elegant vernacular Greek Revival–style dwelling. The house consists of a 1 1/2-story main section, with a slightly lower L-shaped wing. It serves as home for the park superintendent. It was listed on the National Register of Historic Places in 1979.
