23rd Street is a broad thoroughfare in the New York City borough of Manhattan. It is one of few two-way streets in the gridiron of the borough. As with Manhattan's other "crosstown" streets, it is divided at Fifth Avenue, in this case at Madison Square Park, into its east and west sections. Since 1999 the area north of 23rd Street around the park has been referred to as Nomad. The street formerly ran from the East River to the Hudson River, but now terminates at 11th Avenue.

La 23 rue (ou 23rd Street) est une rue de Manhattan, à New York qui constitue l'un des principaux axes de circulation est-ouest du borough. Elle relie l'Hudson River à l'East River en permettant la circulation dans les deux sens, ce qui n'est pas le cas dans la plupart des rues (circulation est-ouest) et des avenues (axes nord-sud).
