WLLR-FM (103.7 MHz) is a radio station licensed to Davenport, Iowa, United States, whose format is modern country music.

[3] KIIK, which initially had a broadcast day of 5 a.m. to 12:30 a.m. before switching to 24 hours, quickly became very popular with Quad Cities-area listeners, and soon became the market's top-rated station.

The format change became effective on May 1, 1989, and fans soon identified the "KUUL Red Radio" (a jumbo-sized boombox replica) with the station at its live remote broadcast sites.

In December 1985, WLLR briefly gained national attention when a disc jockey played the Christmas song "Grandma Got Run Over by a Reindeer" 27 times back-to-back during the morning show.

WLLR's stage at the Mississippi Valley Fair was featured in the Music Video for "Don't Ya Just Wanna Rock and Roll" by Rodney Atkins.
