The Pfarr Log House is a log cabin located near the village of Milford in rural Clermont County, Ohio, United States. Built in the early nineteenth century, it provides a pivotal representation of the area's earliest built environment, and it has been named a historic site. This cabin is known primarily as a property of the Pfarr family because it was purchased by George Pfarr in late 1840 as part of a 21 acre homestead, and it remained in the Pfarr family until it was sold to James Wiederhold in 1976. George, a butcher and farmer, immigrated from Bavaria with his wife and three children, and the property was actively farmed until the 1960s by his children and grandchildren.
