KCBS, 740 AM, is an all-news radio station located in San Francisco, California, which serves as the West Coast flagship station for the CBS Radio Network. It is owned by the CBS Corporation's CBS Radio subsidiary, and shares its Battery Street studios with CBS owned-and-operated television station KPIX-TV (channel 5). The transmitter site is located in Novato. Its programming is simulcast on co-owned FM station KFRC-FM (106.9) plus that station's HD1 digital sub-channel.

KCBS operates with a transmitter output of 50,000 watts, and during the daytime can be regularly received as far north as Sacramento and Hopland and south as far as San Luis Obispo. In good conditions it is also heard as far north as Redding and south to Santa Maria. At night, the station employs a directional antenna, primarily sending its signal to the southeast, in order to protect the coverage of CFZM in Toronto, Ontario, which is the dominant Class A station on the 740 kHz clear-channel frequency. KCBS's nighttime signal is heard throughout California, including Los Angeles and San Diego, in addition to several western states, including Nevada, Oregon, Washington, Idaho and Utah. On rare occasions "DXers" (hobbyists who listen for distant stations) have reported receiving KCBS across the Pacific Ocean, and in Hawaii, Alaska, Colorado and the northwestern portion of Mexico.
