Grindstone Island is the fourth largest of the Thousand Islands in the St. Lawrence River and the second largest of the American islands in the St. Lawrence. The island lies near Lake Ontario and is part of the United States. In particular, the island is part of the Town of Clayton in Jefferson County, New York.
The island contains Potters Beach, a private vineyard, summer gift shops, four active beef farms, historic but now abandoned farmlands, and private non-government conservation lands owned by the Thousand Island Land Trust (TILT). New York State's last operating one-room school was on the island and closed in 1989. The current number of year-round households on the island is ten, however the population climbs to 700 people during the summer months.
