HMCS Stone Town was a River-class frigate that served with the Royal Canadian Navy during the Second World War. She served primarily as a convoy escort in the Battle of the Atlantic. She was named for St. Marys, Ontario, however there was already a ship by that name within the Commonwealth navies so they chose the nickname of the town for its representation. After the war she was re-purposed as a weather ship for use by the Department of Transport of Canada.
