WCBS-FM (101.1 MHz.) is a radio station in New York City, owned by CBS Radio. The station's studios are located in the combined CBS Radio facility at 345 Hudson Street in Manhattan, and its transmitter is located on the Empire State Building.

WCBS-FM was one of the first notable oldies stations in the country, with the format dating back to July 7, 1972. Between June 3, 2005 and July 12, 2007, the station aired an automated adult hits format as "Jack FM," but the format failed. WCBS-FM switched back to a personality-driven classic hits/oldies format, with a more broadened playlist concentrating on music from 1964 to 1989, but unlike many other classic hits stations, it also plays selected older hits from the pre-1964 period as well.
