SS Leafield

{{Short description|Canadian steel-hulled cargo ship that sank in Lake Superior}}

SS Leafield was a Canadian steel-hulled cargo ship built by the Strand Stepway Company in Sunderland, England, in 1892. Originally registered in Newcastle upon Tyne, England, she was sold after about a year to the Algoma Central Steamship Line and brought to Canada, where she operated on the Great Lakes, carrying coal, grain, and iron ore.{{cite web |url=http://images.maritimehistoryofthegreatlakes.ca/57178/data |title=Maritime History of the Great Lakes |accessdate=2017-02-12}}

On the night of 17 August 1912, Leafield was carrying ore to Midland, Ontario, Canada, when she ran aground on a rocky islet in Georgian Bay near Beausoleil Island, Ontario. The incident tore a hole {{convert|140|ft}} long and {{convert|15|ft}} wide in her bottom. Salvage and repairs cost $15,000, and the ship was out of service for two months.

Leafield was hauling steel rails, bound for Midland, when she sank in deep water in Lake Superior, probably off the Angus Rocks in the Angus Islands, about {{convert|14|mi}} southeast of Port Arthur, Ontario, on 9 November 1913 during the Great Lakes storm of 1913. Her entire crew of 18 perished. A search found no trace of the ship or crew. As of 2025, Leafield's wreck has not been located.
