WZIN (104.3 FM) is a radio station licensed to serve Charlotte Amalie, U. S. Virgin Islands. The station is owned by Pan Caribbean Broadcasting de P.R., Inc. It airs an alternative rock format.
The Federal Communications Commission assigned the call letters WSTT to this station on May 23, 1983 until they requested a switch to WCWI on March 15, 1987. This call sign was short-lived as the station would switch calls again on September 13, 1987 to become WIYC. Almost a decade would elapse before the station changed, this time becoming WVPI on February 3, 1997. The station used this legal identifier for more than five years until switching to the current call sign, WZIN, on December 10, 2002.
