WGST (640 AM; "640 ESPN Deportes") is a radio station licensed in the city of Atlanta, Georgia operating at a frequency of 640 kHz with 50,000 watts of power during the daytime, and 1,000 watts of power during nighttime hours. The station is owned by the Clear Channel Communications subsidiary Citicasters Licenses (formerly part of Jacor Communications), and serves the Atlanta metropolitan area media market with a Spanish sports radio format. WGST's programming is simulcast on an HD Radio digital subchannel of sister station WUBL (94.9 FM). The station is also carried on an audio-only, digital sub-channel of the low-powered digital television station WANN-LD in Atlanta.

The facility at 640 started with an application in 1981, with a construction permit granted by the Federal Communications Commission (FCC) in 1985, and the broadcast callsign WPBD issued in 1986. After a series of extensions to the six-month permits and finally a minor modification, it finally went on the air in February 1988. After an initial dismissal later that year, permission to transfer the station to Jacor was granted in 1989, and the WGST format was moved from what is now WGKA (920 AM). The station's nighttime radiation pattern has a null toward the northeast.

An English-language station for the bulk of its history, WGST has been an affiliate of ESPN Deportes Radio since September 28, 2012.
