Dr. Robert B. McNutt House is a historic home located at Princeton, Mercer County, West Virginia. The original section was built about 1840, and is a classic I house configuration, with a two-story, three-bay main facade and a one-bay-wide, two-story centered portico. Later additions include a one-story, hip-roofed section and a two-story ell. The portico has curvilinear brackets and a second story railing in the Gothic Revival style. The house sits on a random ashlar sandstone foundation. Also on the property is a contributing stone storage building / well house. The house was used as a headquarters and field hospital by the Union Army in the spring of 1862.
It was listed on the National Register of Historic Places in 2001.
