KGUM (567 AM) is a radio station licensed to serve the community of Hagåtña, Guam.

Owned by Sorensen Media Group, it broadcasts a news/talk format branded as News Talk K57.

Stations in Guam fall within the jurisdiction of the Geneva Frequency Plan of 1975, instead of the North American Regional Broadcasting Agreement used in the U.S. mainland and Hawaii.

A storm knocked down KGUM's tower in January 2016, requiring the station to broadcast under special temporary authority with 5,000 watts.

K57's weekday daytime and Saturday morning hours are dedicated to locally produced talk shows, while nationally syndicated programs play overnight, Saturday afternoons and Sunday.
