KLUC-FM (98.5 MHz) is a commercial radio station in Las Vegas, Nevada, airing a Top 40/CHR format.

The HD3 subchannel airs a Regional Mexican music format known as "Fiesta 98.1," which feeds FM translator K251BS at 98.1 MHz.

[4] Rainbow, Inc., owner of KRBO 1050 AM (later KXST 1140 AM), obtained a construction permit for a new FM radio station in Las Vegas on March 22, 1961.

The AM station switched its call sign to KLUC, standing for "Lucky," a popular word in the gambling city of Las Vegas.

The studios were first located on Industrial Road and later W Hacienda Ave and the stations were network affiliates of CBS Radio.

[5] The company was renamed Western Cities Broadcasting in 1979 to reflect its station holdings in Las Vegas; Tucson, Arizona; and Sacramento, California.

It was also the recognized primary commercial outlet for urban contemporary and rhythmic music in the city, playing more rap in the evenings.
