Madison Square is a public square formed by the intersection of Fifth Avenue and Broadway at 23rd Street in the New York City borough of Manhattan. The square was named for James Madison, fourth President of the United States. The focus of the square is Madison Square Park, a 6.2-acre (2.5-hectare) public park, which is bounded on the east by Madison Avenue (which starts at the park's southeast corner at 23rd Street); on the south by 23rd Street; on the north by 26th Street; and on the west by Fifth Avenue and Broadway as they cross. The park and the square are at the northern (uptown) end of the Flatiron District neighborhood of Manhattan. The neighborhood to the north and west of the park is NoMad ("NOrth of MADison Square Park") and to the north and east is Rose Hill. Madison Square is probably best known around the world for providing the name of Madison Square Garden, a sports arena and its successor which were located just northeast of the park for 47 years, until 1925. The current Madison Square Garden, the fourth such building, is not in the area. Notable buildings around Madison Square include the Flatiron Building, the Toy Center, the New York Life Building, the New York Merchandise Mart, the Appellate Division Courthouse, the Met Life Tower, and One Madison Park, a 50-story condominium tower.

The Flatiron Building, originally the Fuller Building, is a triangular 22-story, 285-foot-tall (86.9 m) steel-framed landmarked building located at 175 Fifth Avenue in the eponymous Flatiron District neighborhood of the borough of Manhattan, New York City. Designed by Daniel Burnham and Frederick Dinkelberg, it was one of the tallest buildings in the city upon its 1902 completion, at 20 floors high, and one of only two "skyscrapers" north of 14th Street—the other being the Metropolitan Life Insurance Company Tower, one block east. The building sits on a triangular block formed by Fifth Avenue, Broadway, and East 22nd Street—where the building's 87-foot (27 m) back end is located—with East 23rd Street grazing the triangle's northern (uptown) peak. As with numerous other wedge-shaped buildings, the name "Flatiron" derives from its resemblance to a cast-iron clothes iron.Called "one of the world's most iconic skyscrapers and a quintessential symbol of New York City", the building anchors the south (downtown) end of Madison Square and the north (uptown) end of the Ladies' Mile Historic District. The neighborhood around it is called the Flatiron District after its signature, iconic building. The building was designated a New York City landmark in 1966, was added to the National Register of Historic Places in 1979, and was designated a National Historic Landmark in 1989.

At the north (uptown) end of the district is Madison Square Park, which was completely renovated in 2001. The Flatiron District encompasses within its boundaries the Ladies' Mile Historic District and the birthplace of Theodore Roosevelt, a National Historic Site. The Flatiron District was also the birthplace of Silicon Alley, a metonym for New York's high technology sector, which has since spread beyond the area.The Flatiron District is part of Manhattan Community District 5. Residents are represented by the Flatiron Alliance neighborhood association and nearby businesses by the Flatiron/23rd Street Partnership business improvement district, though the two have different (partially overlapping) boundaries.
