KFI (640 AM) is a radio station in Los Angeles, California, owned and operated by iHeartMedia, Inc. It began operations in 1922 and became one of the first high-powered, clear-channel Class A stations. It was the first U.S. station west of Chicago to broadcast at 50,000 watts.^[1]

Studios and offices are in Burbank, between the Warner Bros. Studios and The Burbank Studios. The transmitter site is in La Mirada near the Artesia Boulevard exit of Interstate 5, the Santa Ana Freeway. By day, its signal can be heard throughout Southern California, with city-grade coverage as far as San Diego, Santa Barbara and Tijuana, and secondary coverage as far as Bakersfield and northwestern Mexico, and at times can be heard some distance into Nevada and Arizona. At night, it can be heard across much of the western half of North America.

KFI and KNX (AM 1070 and 97.1 FM) serve as the primary entry points for the Southern California Emergency Alert System, which are responsible for activation of the EAS when hazardous weather alerts, disaster area declarations, and child abductions are issued.^[2]

KFI is licensed by the U.S. Federal Communications Commission to broadcast in the HD (hybrid) format;^[3] however, it was reported that KFI turned off its HD signal as of August 12, 2015.^[4]^[5] Like other stations owned by iHeartMedia, KFI uses iHeartRadio to stream its webcast.
