WNSL (100.3 FM, "SL100") is a top 40 (CHR) music formatted radio station licensed to Laurel, Mississippi, serving the Laurel-Hattiesburg Arbitron market.

WNSL-AM-FM was founded by Granville Walters, a former news reporter and host at WAML, the first radio station in Laurel.

WNSL successfully tapped into the Hattiesburg market, targeting students at the University of Southern Mississippi, competing with Top 40 station WHSY "Y-104".

This campaign proved to yield little fruit, and within 18 months, the legal identification was changed back to WNSL Laurel-Hattiesburg and Mike Golden was gone.

Holladay expanded the company through acquisition of other stations but eventually sold WNSL and WQIS to Design Media in 1988.

The building where WNSL Studios was for over 40 years in Laurel, MS has been torn down, leaving an old transmitter shed, the foundation and the parking lot.
