KWWN (1100 AM) is a commercial radio station licensed to Las Vegas, Nevada, and airing a sports radio format. It is owned by Lotus Communications with studios on West Flamingo Road in Spring Valley while using a Las Vegas address. KWWN carries a mix of local sports shows and ESPN Radio hosts. Live sports heard on KWWN include the UNLV Rebels football and men's basketball teams along with the Las Vegas Aces of the WNBA and the Los Angeles Lakers of the NBA.

By day, KWWN is powered at 22,000 watts. But at night, to protect other stations on 1100 AM, a clear channel frequency, KWWN reduces power to 2,000 watts and uses a directional antenna with a four-tower array. The transmitter is off North Martin Luther King Boulevard near West Brooks Avenue in North Las Vegas. Programming is also heard on 35-watt FM translator K265EZ at 100.9 MHz in Henderson.

The station signed on the air in December 2007; 17 years ago (December 2007), after running test transmissions for several months. These tests were mainly to arrange the nighttime directional signal of the station, so it would not interfere with nearby KNZZ in Colorado or other stations on 1100 kHz. While testing, the station ran at half power (10,000 watts day and 1,000 watts night) to further limit the possibility of interference. 1100 AM is a United States clear-channel frequency, on which WTAM in Cleveland, Ohio, is the dominant Class A station. Upon signing on, the station began running at its authorized power.

Originally, KWWN simulcast the sports format of its sister station, KBAD 920 AM. In 2008, the simulcast ended. KBAD became the local network affiliate of Fox Sports Radio, while KWWN picked up the ESPN Radio affiliation. KENO, which had run Fox Sports, joined ESPN Deportes Radio and its Spanish-language sports format.

KWWN is the flagship station of the Las Vegas Aces of the Women's National Basketball Association. Before the start of the 2018–19 season, the station was named as an affiliate of the Los Angeles Lakers Radio Network as Las Vegas doesn't have a team in the National Basketball Association
