Seal Island is a small island off the northwest coast of Anguilla.

It is located two kilometres to the east of the Prickly Pear Cays at 18° 16' N, 63° 9' W, and lies at the centre of the Seal Island Reef System Marine Park.

The area is popular with scuba divers.

A reef lying between the island and Anguilla can make access more difficult.
