Ruby was a ship used to deport Acadians from Île Saint-Jean (Prince Edward Island) to France as part of the Île Saint-Jean Campaign during the Seven Years' War.
The ship hit the rocks on Pico Island (Azores) and sank on December 16, 1758, with the loss of 193 lives.
Together with Duke William, John, Samuel, Neptune, Violet, Yarmouth, and another unknown ship, Ruby was part of a fleet that left on November 25 from Port-la-Joye, Île Saint-Jean (Prince Edward Island) for France.
On December 12, Violet sank with all hands lost, and the next day Duke William also went down.
Ruby reached the Azores, but hit the rocks and sank on 16 December.
