The Tally Toor is the local name for a Martello tower in Leith, Edinburgh, Scotland. It is one of Scotland's three Martello towers, the other two being at Hackness and Crockness in Orkney. Originally built offshore on a rocky outcrop called the Mussel Cape Rocks, the land around it was subsequently reclaimed, and the building now lies, half-buried, in an industrial area on the eastern breakwater of Leith Docks.
