Ballard Down is an area of chalk downland on the Purbeck Hills in the English county of Dorset. The hills meet the English Channel here, and Ballard Down forms a headland, Ballard Point, between Studland Bay to the north and Swanage Bay to the south. The chalk here forms part of a system of chalk downlands in southern England, and once formed a continuous ridge between what is now west Dorset and the present day Isle of Wight. Old Harry Rocks, just offshore from the dip slope of the down, and The Needles on the westernmost tip of the Isle of Wight, are remnants of this ridge.
