Nancy was a sloop launched in 1803 and wrecked on 18 April 1805 near Jervis Bay, Australia.

Nancy was a sloop of some 20 tons constructed on the Hawkesbury River, New South Wales by Kable & Co.

On 18 April 1805, Nancy commanded by Captain Demaria was just off Jervis Bay when a violent squall hit the area.

Everything on board was washed overboard and then the ship struck a small sandy beach between two headlands.

The ship promptly broke up with one crew member, Richard Wall, from Exeter, drowning.
