Brooksville is a town in Hancock County, Maine, United States. It contains the villages of North Brooksville, South Brooksville (on Buck's Harbor), West Brooksville, Brooksville Corner, and Harborside (on Cape Rosier). The surface of the town abounds with granite, and several quarries were established. The soil is a clay loam, which yielded wheat and potatoes. Buck's Harbor, safe and deep, is one of the best coves in the region for small boats, and many residents became involved in the coasting trade and fisheries. By 1880, when the population was 1,419, Brooksville had a porgy oil factory, two sawmills, a shingle mill, a planing mill, two gristmills, a wool carding mill, and a cloth and yarn factory.
