Shubert Alley is a pedestrian alley in the Theater District of Midtown Manhattan in New York City. The alley, a privately owned public space, connects 44th and 45th Streets and covers about 6,400 square feet (590 m2). It runs through the middle of a city block, parallel to Eighth Avenue to the west and Broadway to the east. The western half of the alley abuts the Shubert and Booth theaters, while the eastern half is adjacent to One Astor Plaza. Because it is near several major theaters, the alley has been considered the geographical center of Broadway theatre.

One Astor Plaza, also known as 1515 Broadway and formerly the W. T. Grant Building, is a 54-story office building on Times Square in the Theater District of Midtown Manhattan in New York City. Designed by Der Scutt of Ely J. Kahn & Jacobs, the building was developed by Sam Minskoff and Sons. One Astor Plaza occupies a site bounded by Broadway to the east, 45th Street to the north, Shubert Alley to the west, and 44th Street to the south. The building is named for the Hotel Astor, which had occupied the site from 1904 to 1967. SL Green Realty and Allianz own One Astor Plaza, which as of 2022 serves as the headquarters for Paramount Global.
