WNOO (1260 AM) is an urban contemporary/gospel station serving the Chattanooga, Tennessee market, in the United States.

In addition to the main station, WNOO is relayed by an FM translator in order to widen the broadcast area, especially at night when WNOO AM reduces power to 25 watts.

On December 30, 1960, Jerry Tucker of WNOO interviewed Dr. Martin Luther King Jr. just before the civil rights leader gave a speech at Chattanooga's Memorial Auditorium.

[2] On January 1, 2006, WTUN started simulcasting with WNOO after its classic country format was moved to WNGA.

After a few months of simulcasting with WNOO, WTUN 101.9 then changed their calls to WOCE and is now a Spanish-language broadcaster.
