The 53rd Street Library is a branch of the New York Public Library at 18 West 53rd Street, just west of Fifth Avenue in Midtown Manhattan, New York City. The building is located on the south side of 53rd Street, across from the Museum of Modern Art, and adjacent to 660 Fifth Avenue to the east. The library occupies the ground story and two basement levels of a 46-story hotel and residential building.
It opened in 2016 as a replacement for the Donnell Library Center, which occupied a building at 20 West 53rd Street. The Donnell Library Center operated from 1955 until 2008, when it was replaced by the current 46-story building.
