Castle Tioram (pronounced "Chee-rum" from Scottish Gaelic "Caisteal Tioram" meaning "dry castle") is a ruined castle that sits on the tidal island Eilean Tioram in Loch Moidart, Lochaber, Highland, Scotland. It is located west of Acharacle, approximately from Fort William. Though hidden from the sea, the castle controls access to Loch Shiel. It is also known to the locals as "Dorlin castle" The castle is now in extremely poor condition and in 1998 was closed to the public at the request of Highland Council; a major structural collapse occurred at the north west curtain wall in 2000.
