KXLF-TV (channel 4) is a television station in Butte, Montana, United States, affiliated with CBS.

It was an extension of KXLF radio, part of Ed Craney's regional Z-Bar Network.

In 1970, KXLF-TV spawned KPAX-TV in Missoula, which originally was a full-time satellite station but began producing local programming in 1977.

KXLF-TV viewers continued to receive newscasts consisting of Butte inserts into KTVQ's news until January 1989.

Some of Butte's local shows in the 1950s were The Oldtimer, featuring John Diz, This Afternoon with You, hosted by Darien Carkeet, What's New?

When KXLF-TV signed on the air, it operated from studios on the upper floor of a Pay 'n Save food and drug store on Harrison Avenue.

[22][23] After the change, KXLF-TV became a primary affiliate of CBS; this generated outcry in 1962 when the station refused to carry the World Series from NBC because the picture it could receive from KMSO-TV in Missoula was "not of broadcast quality".

[36] SJL sold KXLF, KPAX-TV, and KRTV to the Evening Post Publishing Company, through its Cordillera Communications subsidiary, for $24 million in 1986.

[38] During the early 2000s, KXLF-TV had a secondary affiliation with UPN;[39] the network shut down in 2006 as part of the formation of The CW, which is seen on a digital subchannel of KXLF and KBZK.

After the DTV conversion on June 12, 2009, KXLF was one of more than 10 stations asking for a power increase because of the problems with VHF digital signals, particularly low-VHF frequencies.

[51] In 2021, Scripps filed to switch all of the full-power MTN stations, including KRTV, from the VHF to the UHF band in order to improve reception; it has requested channel 15 for KXLF-TV.

[32] While KPAX and KRTV began offering full-length local news programs in 1986, upon the Evening Post purchase, KXLF continued to produce inserts into KTVQ's newscasts in an arrangement that was set to expire in December 1988.

[56] Kearney sued KXLF-TV and Evening Post in December 1989, seeking compensation for unpaid overtime and four years in lost wages.

[55] The wrongful discharge suit went to trial in 1992; testimony centered around Kearney's ill temper during a November 1988 newscast and other workplace behavior issues.
