Woodhouses hill fort is an Iron Age hillfort between Frodsham and Helsby in Cheshire, England. It lies at the northern end of the Mid Cheshire Ridge. Woodhouse Hill has steep cliffs on the western sides, providing a natural defence. It is defended by a rampart to the north and east where the ground slopes more gently. Excavations in 1951 showed that the rampart was originally 4m high and revetted with stone on both sides. A number of small rounded stones, believed to be slingstones, have been found on the site.
