HMS Rover was a 16-gun sloop-of-war that the Royal Navy purchased in 1796, commissioned in 1798, and that was wrecked in early 1798.

She was last in Porto Rico and had captured three American ships:[3] Rover was wrecked in the Gulf of St Lawrence on 23 June 1798, but her crew were saved.

When lookouts spotted breakers ahead early in the evening it was too late to turn her and she struck rocks on Cape Breton Island.

Eventually a seaman was able to swim to shore with a line that the crew then used to leave Rover, which was by then filling rapidly with water.

All the men reached the shore and the crew finally abandoned her on 26 June, at which time they sailed her boats to Sydney, Nova Scotia.
