HMCS Wentworth 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 in honour of the town of Dartmouth, Nova Scotia. She could not be named HMCS Dartmouth for fear of confusion with HMS Dartmouth, and so was named after a famous early resident, Nova Scotia Lieutenant Governor Sir John Wentworth. Her name is often mistakenly associated with Wentworth County, Ontario, in honour of the city of Hamilton.
