WTBU (95.3 FM, "The Bull") is a radio station licensed to York Center, Maine, United States.

Established in 1987, WTBU is owned by iHeartMedia and serves York County, Maine, and the New Hampshire Seacoast.

At the announced time, the station relaunched as "Kiss 95.3", initially simulcasting WXKS-FM from Boston.

On October 4, 2012, sister station WERZ adopted 95.3's old format, and the station began stunting with sounds of ocean waves and occasional bells, along with voiceover Chad Erickson (as well as its website) redirecting Kiss listeners to WERZ, and advising them to tune in the following Tuesday, October 9, at Noon.

At that time, the station flipped to adult hits as "95.3 The Coast", launching with Journey's "Don't Stop Believin'".
