KXNT (840 AM) is a radio station licensed to North Las Vegas, Nevada, USA. It is owned by CBS Radio and carries a talk radio format The station's studios are located in the unincorporated Clark County area of Spring Valley, while KXNT's transmitter is located near Nellis Air Force Base and serves the greater Las Vegas area. KXNT is a Class B station operating on a clear-channel frequency; WHAS in Louisville, Kentucky is the dominant Class A station on 840 AM.

In 1997, KVEG changed its calls to KXNT, with the "NT" standing for "News/Talk." Management was looking to head the station in a new direction. KXNT AM 840 began airing syndicating programs like Rush Limbaugh and Coast to Coast AM previously heard on rival station KDWN. Others included Dr. Laura and Bill Handel.
