WNCY-FM (100.3 FM, "Y100") is an American commercial country music formatted radio station licensed to Neenah-Menasha, Wisconsin, that serves the Green Bay and Appleton-Oshkosh areas.

On July 18, 2006, Midwest Communications broke ground on their new, $4.725 million facility in Bellevue, and WNCY moved into the new broadcast center in January 2008.

WNCY and the six other Midwest Communications stations in Northeast Wisconsin are now located in the new facility.

[2] WNCY, along with the other Midwest stations in Green Bay, simulcasts WIXX if a tornado warning is in effect within Northeast Wisconsin.

100.3 was WEMI-FM at 100.1 until it moved to its current frequency of 100.3 on May 17, 1995, and started their country format.
