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.

He continued building between Third Avenue and Lexington Avenue up to 104th Street, a section of the city sometimes known at the time as "Duffyville".The hill marked the site of cable car accidents by 1897, as the cars had to quickly accelerate and decelerate at this point.
