WQRF-TV (channel 39) is a television station in Rockford, Illinois, United States, affiliated with the Fox network.

Overcoming a four-month wait to finally get on-the-air, WQRF's first program was an episode of the classic sitcom Gomer Pyle, U.S.M.C..

Orion Broadcasting sold WQRF to Family Group Broadcasting in May 1986, sharing ownership and graphical imaging with WGBA-TV in Green Bay, Wisconsin, WVFT-TV in Roanoke, Virginia, WPGX in Panama City, Florida, WFGX in Fort Walton Beach, Florida, and WLAX in La Crosse, Wisconsin.

For the network's first three years of existence, cable subscribers watched Fox through Chicago's WFLD, Madison's WMSN-TV, or Milwaukee's WCGV-TV, depending on the location.

The broadcast only aired on weeknights unlike the area's original prime time show that was seen every night on cable-only WB affiliate "WBR" (produced by WREX).

Eventually, WQRF expanded Fox 39 News at 9 to a seven-night operation and lengthened the weeknight version to a full hour.

The station's signal is multiplexed: WQRF-TV shut down its analog signal, over UHF channel 39, on February 17, 2009, the original target date on which full-power television stations in the United States were to transition from analog to digital broadcasts under federal mandate (which was later pushed back to June 12, 2009).
