KSFO is a talk radio station in San Francisco, California, USA, broadcasting on 560 kHz AM with content focusing on conservative talk. It operated under the ownership of the American Broadcasting Company (ABC) until the radio group was purchased by Citadel Broadcasting in 2007. The station is now owned by Cumulus Media, following its 2011 merger with Citadel.

The content of the KSFO's talk programming is conservative, with show hosts such as Sean Hannity, Mark Levin, and Laura Ingraham. The station also airs Coast to Coast AM and The Mutual Fund Show with Adam Bold. KSFO operates in the liberal majority San Francisco bay area. The station is co-owned and located with news-only KGO-AM.

KSFO went on the air in 1925. In its heyday, starting in 1955, it played MOR and jazz music, sports, and, particularly memorably, rebroadcast antique radio shows at particular times of the year. At the time, the station was owned by Gene Autry's Golden West Broadcasters and called itself "the world's greatest radio station." KSFO's signature jingle, "The Sound of the City" (written by Johnny Mann and sung a cappella by the University of California Men's Octet), became legendary in San Francisco — reportedly requested by listeners as much as any popular song on the station's playlist — and was subsequently adopted by other like-formatted stations around the country. Memorable broadcasters of KSFO's history include Russ Hodges, Lon Simmons, Don Sherwood, Jeff Skov, Aaron Edwards, Jim Lange, John Gilliland, Gene Nelson, Dan Sorkin and Jim Eason. The station's history included stints as the flagship station for both San Francisco Giants and Oakland Athletics baseball (at different times) and San Francisco 49ers, University of California and Stanford University football. A history of KSFO in the heyday of Don Sherwood (1950s and 1960s) can be found in Laurie Harper's biography, "Don Sherwood — The World's Greatest Disk Jockey."
