KGO (810 kHz) is a commercial AM radio station in San Francisco, California. It airs a sports betting format and is owned by Cumulus Media. Its offices and studios are on Battery Street in the SoMa portion of San Francisco's Financial District.

KGO's transmitter site is in Fremont, near the Dumbarton Bridge, where its prominent towers are landmarks used by pilots as a waypoint in communications with local airports. KGO broadcasts with 50,000 watts, the highest power permitted for AM stations by the Federal Communications Commission (FCC). It uses a directional antenna fulltime with a three-tower array.^[2] Most of its signal is sent north and south to avoid interfering with the other Class A station on 810 kHz, WGY in Schenectady, New York. Most nights, using a good radio, KGO can be heard throughout the Western United States and Western Canada. Due to its extensive groundwave signal, its daytime coverage extends into many areas of Northern California.
