Brantwood is an unincorporated community in southern Price County, Wisconsin, United States located within the town of Knox. It lies along United States Highway 8 and on the Wisconsin Central Railroad, between Prentice on the west and Tomahawk on the east. The rural community was settled in the late 1890s as a logging community.Francis Palms was the first to purchase acreage in the area and later sold the land to William and Samuel Knox. The Knox brothers were loggers from the Stevens Point, Wisconsin area. They established the small community of Knox Mills a few miles south of Brantwood when they built a mill. The need to transport timber and products resulted in a spur being built from Brantwood to Knox Mills.J. B. Engstrom owned a sawmill, planing mill, and a boarding house for the mostly immigrant bachelor workers in Knox Mills. The mill prospered in the 1920s, but the Great Depression shut it down until the late 1930s.
