West Kingston is an unincorporated village in the town of South Kingstown in the U.S. state of Rhode Island. West Kingston is the site of the Kingston Railroad Station Amtrak station. Before Rhode Island abolished county government, West Kingston was the county seat of Washington County, Rhode Island for many years, although it itself is a village and therefore hosts no local government.
Although unincorporated, West Kingston has a post office and recognized mailing address location. It shares zip code 02892 with much of western South Kingstown, a large portion of Richmond, Rhode Island to the west, and small parts of Exeter, Rhode Island to the north.
