WRDV is a U.S. public radio station serving some northern suburbs of the Philadelphia, Pennsylvania area.

WRDV's program hosts are volunteers who frequently play their own album collections on the air.

WRDV began broadcasting on September 6, 1976 as WCSD, a 10-watt radio station located at the former William Tennent High School on Street Road.

Its call letters are the initials of the station's original owner, the Centennial School District.

In 1981 it increased power to 200 watts and in 1986 its callsign changed to WRDV which stand for "Radio in the Delaware Valley."
