The Caribbean monk seal (''Neomonachus tropicalis''), also known as the West Indian seal or sea wolf, was a species of seal native to the Caribbean which is now believed to be extinct.

The last confirmed sighting of the Caribbean monk seal was in 1952 at Serranilla Bank, between Jamaica and Nicaragua. In 2008, the species was officially declared extinct by the United States, after an exhaustive five-year search.
