KWPN (640 kHz, "ESPN Radio 640") is a commercial AM radio station licensed to Moore, Oklahoma, and serving the Oklahoma City metropolitan area. It is owned by Cumulus Media and airs a sports format. While Cumulus owns three sports stations in Oklahoma City, WWLS-FM and WKY have mostly local shows on weekdays, while KWPN carries mostly syndicated programming from ESPN Radio. The studios and offices are on NW 64th Street in Northwest Oklahoma City.^[2]

KWPN's transmitter is off West Indian Hills Road in Norman.^[3] It broadcasts with a power of 5,000 watts by day; because AM 640 is a clear channel frequency, reserved for Class A KFI in Los Angeles, KWPN must reduce power to 1,000 watts at night to avoid interference. A directional antenna is used at all times.
