Blackwell House is an historic house on Roosevelt Island (formerly known as Welfare Island) in New York City.

After the English defeated the Dutch in 1666, Captain John Manning seized the island, which became known as Manning's Island, and twenty years later, Manning's son-in-law, Robert Blackwell, became the island's new owner and namesake.[2]

In 1796, Blackwell's great-grandson Jacob Blackwell constructed the Blackwell House, which is the island's oldest landmark, New York City's sixth oldest house, and one of the city's few remaining examples of 18th-century architecture.[2]

It was added to the National Register of Historic Places in 1972.
