The Ansonia is a condominium building at 2109 Broadway, between 73rd and 74th Streets, on the Upper West Side of Manhattan in New York City. The 17-story structure was designed by French architect Paul Emile Duboy in the Beaux-Arts style. It was built between 1899 and 1903 as a residential hotel by William Earle Dodge Stokes, who named it after his grandfather, the industrialist Anson Greene Phelps. Over the years, the Ansonia has housed many conductors, opera singers, baseball players, and other famous and wealthy people. The Ansonia is a New York City designated landmark and is listed on the National Register of Historic Places.

Broadway is a road in the U.S. state of New York. Broadway runs from the south at State Street at Bowling Green for 13 mi (20.9 km) through the borough of Manhattan, over the Broadway Bridge, and 2 mi (3.2 km) through the Bronx, exiting north from New York City to run an additional 18 mi (29.0 km) through the Westchester County municipalities of Yonkers, Hastings-On-Hudson, Dobbs Ferry, Irvington, Tarrytown, and Sleepy Hollow, after which the road continues, but is no longer called "Broadway". The latter portion of Broadway comprises a portion of U.S. Route 9.
