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 Founding Father James Madison, the 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.
