Weekapaug is a small fire district in southern Washington County, Rhode Island, part of the town of Westerly, Rhode Island. It is a small beachfront community that is also a census-designated place. Weekapaug lies in the Eastern Time Zone and observes daylight saving time.
"Weekapaug" is an American Indian word meaning "end of pond". The area is not as well known as neighboring Watch Hill, Rhode Island, even though it has had summer cottages since 1877. It was known as Noyes Beach from 1701 to 1899, named after Reverend James Noyes who purchased 300 acres (1.2 km2).
In 1899, Frederick and Phebe Buffum opened the Weekapaug Inn for a summer season of guests. The Hurricane of 1938 swept the barrier beach clean of houses on September 21, 1938 and damaged the Inn, but it was rebuilt and reopened for guests the following June.
The Winnapaug and Quonochontaug salt ponds dominate the area. Each pond is open to the Atlantic Ocean via a breachway lined with rock jetties. Most of the rock is granite which is readily available in the Westerly area and used to be its primary industry.
