The Ivory McKusick House is a historic house in Stillwater, Minnesota, United States, completed in 1872 for Ivory McKusick (1827–1906). It was listed on the National Register of Historic Places in 1982 for having local significance in the themes of architecture and commerce. It was nominated as a striking example of Second Empire architecture in the region and for its associations with a notable family in early Stillwater. McKusick had built his wealth via the lumber industry and government contracts during the Civil War. His older brother John had helped establish the first sawmill in the vicinity in 1843, named and platted the community that grew around it after his hometown in Maine, and served as its first mayor.
