HMS Dunvegan Castle was a UK ocean liner that was converted into an armed merchant cruiser (AMC) in the Second World War. Harland and Wolff built her and her sister ship Dunnottar Castle in Belfast in 1936. Union-Castle Line operated Dunvegan Castle on scheduled services between Southampton and South Africa until 1939. When war broke out she was requisitioned by the Admiralty and commissioned as HMS Dunvegan Castle.
