KXST (1140 AM) was a commercial radio station licensed to North Las Vegas, Nevada, and broadcasting to the Las Vegas metropolitan area. The station was owned by Audacy, Inc. It aired a sports radio and sports betting format, primarily from the co-owned BetQL Network and the CBS Sports Radio Network. That programming continues on 98.5 KLUC-FM-HD2, also owned by Audacy.

KXST's transmitter was near Nellis Air Force Base and Interstate 15, on East Tropical Parkway; the sale of the site is a factor in the station's closure. Its transmitter power output was 10,000 watts by day, using a non-directional antenna. Because AM 1140 is a clear channel frequency reserved for XEMR in Monterrey, Mexico, and WRVA in Richmond, Virginia, KXST reduced its power to 2,500 watts and used a directional antenna at night.
