KZSF (1370 AM) is a broadcast radio station in the United States. Licensed to San Jose, California, KZSF serves the San Francisco Bay Area and has a regional Mexican music format branded "La Kaliente 1370 AM." The station has been owned by Carlos A. Duharte since 2001.

For much of its history, KZSF has been a music radio station. Founded by George Mardikian and United Broadcasting Company, the station signed on with call sign KEEN in 1947 and operated out of the historic Hotel De Anza in San Jose for its first 27 years. After beginning with a general full service format, KEEN became a country and western station in the mid-1950s and would retain that format for over 35 years, with performers such as Red Murrell and Foy Willing among its on-air hosts. KEEN also featured live sports coverage; it broadcast the San Jose State Spartans and Santa Clara Broncos in the late 1950s and throughout the 1960s and the Oakland Athletics during the early to mid-1970s.

In 1993, KEEN went silent for several months after losing its transmitter license and returned to the air in 1994 as KKSJ and a pop standards format branded "Magic 1370." Founding owner United Broadcasting sold the station in 1997. After one year with an Asian ethnic format, KKSJ became KZSF in 1998 and took on its present regional Mexican music format. KZSF would be sold twice more in the late 1990s before finally being purchased by Duharte in 2001.
