KCWO-TV (channel 4) is a television station licensed to Big Spring, Texas, United States, serving the Permian Basin area as an affiliate of The CW Plus. It is owned by Gray Television alongside CBS affiliate KOSA-TV (channel 7), MyNetworkTV affiliate KWWT (channel 30), Telemundo affiliate KTLE-LD (channel 20) and Antenna TV affiliate KMDF-LD (channel 22). The five stations share studios inside the Music City Mall on East 42nd Street in Odessa, with a secondary studio and news bureau in downtown Midland; KCWO-TV's transmitter is located on US 87 north of Big Spring.

Until January 2019 as KWAB-TV, the station operated as a satellite of Odessa-licensed NBC affiliate KWES-TV (channel 9), then owned by Raycom Media. KWAB-TV's signal covered eastern parts of the Odessa–Midland market that received a marginal to non-existent over-the-air signal from KWES-TV, although there was significant overlap between the two stations' contours otherwise. KWAB-TV was a straight simulcast of KWES-TV; the only on-air references to the station were during Federal Communications Commission (FCC)-mandated hourly legal identifications. Aside from the transmitter, KWAB-TV/KCWO-TV does not maintain any physical presence locally in Big Spring. In conjunction with Gray's acquisition of Raycom and subsequent resale of KWES-TV to Tegna Inc., KWAB-TV was retained by Gray and converted into a stand-alone station; its main channel is simulcast in high definition on KOSA-TV's second digital subchannel to expand its broadcast range.
