SS Ben Seyr was an steel-built coastal cargo vessel which was operated out of Ramsey, Isle of Man for the Ramsey Steamship Company; ostensibly to Liverpool, Belfast and Whitehaven. Her name, Ben Seyr, came from the Manx Gaelic term for gentlewoman. She was lost in a storm in either the northern part of the Celtic Sea, or the southern part of the Irish Sea, in October 1938, going down with the loss of all hands.
