Herald Square is formed by the intersection of Broadway, Sixth Avenue (officially named Avenue of the Americas) and 34th Street in the borough of Manhattan in New York City. Named for the New York Herald, a now-defunct newspaper originally headquartered there, it also gives its name to the surrounding area. The intersection is a typical Manhattan bow-tie square that consists of two named sections: Herald Square to the north (uptown) and Greeley Square to the south (downtown). Most non-New Yorkers know of it from the song Give My Regards to Broadway where the singer asks "remember me to Herald Square", or from the fact that Herald Square is the terminus for the Macy's Thanksgiving Day Parade, broadcast nationally each year by NBC-TV.

Greeley Square lies between West 32nd Street and West 33rd Street and between Broadway and Sixth Avenue, and is taken up almost entirely by a triangular park. It is named after Horace Greeley, who was the publisher of the New York Tribune, the Herald's rival newspaper. (The two papers later merged to form the New York Herald Tribune.) There is a statue of Greeley inside the park, created in 1890 by Alexander Doyle The small park has great deal of charm, it is planted with trees and shrubbery, enclosed by a wrought-iron fence, and provided with inviting chairs, tables and a restaurant kiosk.

Herald Square itself is the north end of the square between West 34th Street and West 35th Street. The old New York Herald Building was located on the square. The square contains a huge mechanical clock whose mechanical structures were constructed in 1895 by the sculptor Antonin Jean Carles.

Since 1992, Herald and Greeley Squares have been operated by the 34th Street Partnership, a Business Improvement District (BID) operating over 31 blocks in midtown Manhattan. The 34SP provides sanitary and security services, maintains a horticultural program that includes trees, gardens, and planters, and produces events, product launches, and photo shoots. 34SP also added movable chairs, tables, and umbrellas, to the parks. In 1999, the parks were completely renovated by 34SP. Since 2008, each park has had a food kiosk operated by 'wichcraft, the highly regarded sandwich, soup and salad purveyor owned by Tom Colicchio of "Top Chef" fame. In 2009, 34SP converted the parks' Automated Pay Toilets into free public facilities, a rarity in New York City.

With the introduction of "Broadway Boulevard", a project by the NYC Department of Transportation to close Broadway to vehicles on the stretch between 33rd and 35th Streets, the passive space provided by Herald and Greeley Squares more than doubled, radically changing the character of the area. The parks' operators, 34SP, filled the newly-pedestrianized space with chairs, tables, umbrellas, and free public programs such as chess tables, dance lessons, and exercise classes.

Herald and Greeley Squares stand today as rest areas for the thousands of shoppers that flood the neighborhood, as a lunchroom for thousands of midtown office workers, and as a stage for product launches, musical performances, and photo and film shoots.

The area around Herald Square along Broadway and 34th Street is a retail hub. The most notable attraction is the Macy's flagship department store, the largest in the United States (and according to Guinness World Records the largest in the world). In 2007, Macy's, Inc. moved its corporate headquarters to that store after renaming from Federated. Macy's archrival Gimbels was also located in the neighborhood until 1984; in 1986 the building became the Manhattan Mall. Other past retailers in the area included E.J. Korvette, Stern's, and Abraham & Straus. J.C. Penney opened its first Manhattan flagship store in August 2009 at the former A&S location inside the Manhattan Mall. The square is roughly equidistant between Madison Square to the south, and Times Square to the north. Herald Square's south side borders Koreatown, at West 32nd Street. The area is served by the 34th Street – Herald Square station (B D F M N Q R trains) and the 33rd Street station (HOB–33, JSQ–33 trains) of the PATH.
