The Interchurch Center is a 19-story limestone-clad office building located at 475 Riverside Drive and West 120th Street in Morningside Heights, Manhattan, New York City. It is the headquarters for the international humanitarian ministry Church World Service, and also houses a wide variety of church agencies and ecumenical and interfaith organizations as well as some nonprofit foundations and faith-related organizations, including the Religion Communicators Council. The National Council of Churches also occupied the building from its inception, but in February 2013, the NCC consolidated its offices on Capitol Hill in Washington, DC, and vacated its New York headquarters facilities. NCC's sister agency, Church World Service, remains a tenant in the building.

Riverside Drive is a scenic north–south avenue in the New York City borough of Manhattan. The road runs on the west side of Upper Manhattan, generally paralleling the Hudson River and Riverside Park between 72nd Street and the vicinity of the George Washington Bridge at 181st Street. North of 96th Street, Riverside Drive is a wide divided boulevard. At several locations, a serpentine service road diverges from the main road, providing access to the residential buildings. The avenue was opened in 1880, and several viaducts were completed over the subsequent decades to connect the various segments of Riverside Drive.
