KMGH-TV (channel 7) is a television station in Denver, Colorado, United States, affiliated with ABC. It is owned by the E. W. Scripps Company alongside Sterling-licensed independent station KCDO-TV, channel 3 (and its Denver-based translator KSBS-CD, channel 10). The two stations share studios on Delgany Street in Denver's River North Art District; KMGH-TV's transmitter is located atop Lookout Mountain, near Golden.

KMGH-TV operates digital translator KZFC-LD (channel 26) in Windsor, and its main channel is relayed on a digital subchannel of KSBS-CD, allowing homes with issues receiving KMGH's VHF signal or only a UHF antenna to receive KMGH-TV in some form; KCDO-TV also carries a 7.1 subchannel to extend KMGH-TV's over-the-air reach throughout northeast Colorado and western Nebraska. The station's second and third subchannels, which carry Scripps-owned diginets Ion Mystery and Laff, are relayed on translators KZCO-LD (channel 30) in Denver and KZCS-LD (channel 18) in Colorado Springs.

Channel 7 first signed on the air on November 1, 1953, as KLZ-TV. It was founded by the Oklahoma City-based Oklahoma Publishing Company (operated by Edward K. Gaylord), which also owned KLZ radio (560 AM and 106.7 FM, now KWBL).

KLZ-TV immediately took the CBS affiliation from KBTV (channel 9, now KUSA), owing to KLZ radio's longtime affiliation with the CBS Radio Network.

In 1954, Gaylord sold the KLZ television and radio stations to Time Inc., who later subordinated their acquisition under its in 1961 established subsidiary Time-Life, Inc. as Time–Life Broadcasting, Inc.

The station's original studio facilities were housed in a renovated former auto dealership on the east side of the block at East 6th Avenue and Sherman Street. Channel 7 moved to an eight-sided, five-story building called "The Communications Center", on the intersection of Speer Boulevard and Lincoln Street in 1969.

Time-Life sold the station on channel 7 to McGraw-Hill in late October 1970, in a group deal that also involved the company's other radio and television combinations in Indianapolis, San Diego, and Grand Rapids; and KERO-TV (channel 23) in Bakersfield, California. In order to comply with the Federal Communications Commission's new restrictions on concentration of media ownership that went into effect shortly afterward, McGraw-Hill was required to sell the KLZ radio stations as well as their sister radio properties in Indianapolis, San Diego, and Grand Rapids to other companies. Time-Life would later purchase WOTV (channel 8, now WOOD-TV) in Grand Rapids in the final deal. By the time the sale was finalized in June 1972, the purchase price for the entire group was just over $57 million. WFBM-TV (channel 6, now WRTV) in Indianapolis, KERO-TV in Bakersfield, and KOGO-TV (channel 10, now KGTV) in San Diego were retained by McGraw-Hill, along with KLZ-TV, which subsequently changed its call letters to KMGH-TV on the 1st (with the calls reflecting the new ownership), in order to comply with a now-repealed FCC rule in place then that forbade TV and radio stations in the same market, but with different ownership from sharing the same callsigns.

The 1990s did not begin well for KMGH; the station saw significant overall financial losses in 1990 and 1991, as well as a decrease in viewership for its local newscasts. A new management team introduced in 1991 turned things around at KMGH; net profit soared 105.5% in 1992 as a result.
