The Hoag Gristmill and Knight House Complex is a former industrial site on State Prison Hollow Road in Starksboro, Vermont.

The Hoag Gristmill and Knight House stand in a gorge created by Lewis Creek in rural northwestern Starksboro.

The base is one of the surviving elements of a gristmill established in the 1790s by Joseph Hoag, a prominent Quaker leader in the region.

[2] Also on the north side of State Prison Hollow Road, but across Lewis Creek and east of the mill, stands the Knight House.

Built in the 1820s, its main block is a vernacular five-bay Cape, with attached 1+1⁄2-story ells at its northern end.
