Blackwell House is a historic house on Roosevelt Island in New York City. The house's name comes from Jacob Blackwell, who built the house in 1796. He was the great-grandson of Robert Blackwell, who in 1686 took ownership of what was then known as Manning's Island and subsequently became the island's new namesake.{{cite web |url= http://old.nyc10044.com/timeln/timeline.html |title= Timeline of Island History |publisher= Main Street Wire |url-status= dead |archive-url= https://web.archive.org/web/20150507010705/http://old.nyc10044.com/timeln/timeline.html |archive-date= May 7, 2015 }} The house was added to the National Register of Historic Places in 1972.
