WKST-FM (96.1 MHz), is a commercial radio station licensed to Pittsburgh, Pennsylvania, United States.

The station is owned by iHeartMedia and airs a contemporary hit radio format, branded as 96.1 Kiss.

As disco began to wane in popularity, the station flipped to a rock-leaning top 40 format as WXKX (96KX or "96 Kicks").

On January 17, 1983, faced with new competition from WBZZ (B-94), the station shifted to a more mainstream top 40 format and became "HitRadio 96."

On April 25, 2006, iHeartMedia (then Clear Channel Communications), announced that WKST-FM's HD2 subchannel would carry a format focusing on Dance hits.
