Beacon Hill is one of the highest viewpoints in the hinterland of Poole Harbour, Dorset. Its tree-covered summit reaches 84 metres (276 ft) above sea level and there is a public footpath running roughly north to south over the top. Historically it was one of a series of beacons used to warn of the advancing Spanish Armada. The earlier name for the hill was Lytchett Beacon.
