Duffy's Hill is a hill located on Lexington Avenue between 102nd and 103rd Streets in the East Harlem neighborhood of Manhattan, New York City.

It was named for Michael James Duffy, a Tammany Hall Alderman who spent $250,000 to build 26 rowhouses on the south side of 101st Street between Lexington and Park Avenues in 1894.
