The Whelk Point Fort was a colonial fort erected on the southeast part of Tortola in the British Virgin Islands. The fort fell into disrepair and ruin, and relatively little of the original structure remains. In 1992 a house was built over the original foundations of the fort, but the remains of the barracks can still be seen on the land behind the house. The ruins are on private property and are not generally accessible to the public.
The main fortification was built by the British at the outbreak of the American war of independence. The fort guarded two strategic locations. Primarily, the fort overlooks the narrow passage entering Paraquita Bay to the west - one of the largest natural harbours in the British Virgin Islands and the natural gateway to one of the relatively few large agricultural areas on Tortola. The passage into Paraquita Bay is extremely narrow to navigate in any event with the wind and waves surging directly into the gap, and it would be almost impossible to make the entrance in an eighteenth-century sailboat under immediate fire from the fort only 100 meters away.
