CKYY-FM (89.1 MHz) is a commercial radio station in Welland, Ontario, Canada, serving the Niagara Region.

The studios and offices for CKYY-FM and sister station CIXL-FM are on Forks Road on the Port Colborne - Welland border.

The tower has a height above average terrain (HAAT) of 130.5 meters (428 ft).
