The John Olness House is a house in Kragnes Township, Clay County, Minnesota, just north of Moorhead on U.S. Route 75. The house is listed on the National Register of Historic Places as an example of a link between the farm communities and the farm-related businesses in Clay County. The architecture shows influences of the Queen Anne style, which stands out in Clay County because most buildings were in the local vernacular style. The owner, John Olness, was a successful farmer, and he also owned several businesses in the nearby community of Kragnes, including the local grain elevator and lumber yard.
