Just Room Enough Island (Smallest Inhabited Island in World), Thousand Islands Chain, belonging to New York, United States

Just Room Enough Island, also known as Hub Island, is an island located in the Thousand Islands chain, belonging to New York, United States. The island is known for being the smallest inhabited island in world, which appears to be around 3,300 square feet (310 m2), or about one-thirteenth of an acre. Purchased by the Sizeland family in the 1950s, the island has a house, a tree, shrubs, and a small beach.

The island was bought in the 1950s by the Sizeland family, who  wanted a holiday getaway and built a house there. Because of the island's small size, in 2010, the  Washington Post stated, "One misstep and  you're swimming".

Just Room Enough lies on the Saint Lawrence River between  Heart  Island and Imperial Isle, close to the US border with Canada. The island belongs to  Alexandria  Bay, a village part of the town of Alexandria, Jefferson County, New  York.

While the Sizelands had hoped for their quirky little getaway to be a nice respite from the hustle and bustle of city life, it soon attracted hordes of sightseers and tourists who broke their placid solitude.

In order to be considered an island in the region, the land must be larger than one square foot, it must remain above the water level year round, and it must sustain at least one tree. Just Room Enough Island meets these criteria, but really it’s more house than island. The islands are just five hundred feet away from Boldt Castle, the iconic storybook mansion that George Boldt began building in 1900.
