KNUJ-FM (107.3 MHz) is a radio station in Sleepy Eye, Minnesota.

The station airs a classic hits format, as "SAM 107.3", and is owned by James Ingstad.

The 4,000-watt station licensed to nearby Sleepy Eye played adult contemporary music.

Two years later, Cumulus turned around and sold some of the stations, including KNUJ and KNUJ-FM to Clear Channel.

After the shutdown of the Sam FM network, KNUJ shifted to classic hits during the Labor Day weekend of 2015.
