KLSD (1360 AM) is a commercial radio station in San Diego, California, broadcasting a conservative talk radio format branded as "The Patriot." It is owned by iHeartMedia with studios on Granite Ridge Drive. Programming is also heard on FM translator K227DH at 103.3 MHz.

Founded in 1922 with call sign KFBC, KLSD is San Diego's oldest licensed radio station. For much of its early history, it had the call sign KGB from 1928 to 1982. Art Linkletter was an announcer and later station manager for KGB radio in the 1930s. During the KGB era, the station had different music formats, including top 40 from 1965 to 1972 and 1974 to 1982, album-oriented rock from 1972 to 1974.

Beginning in the 1980s, KGB had several changes in identity and management. The station became KCNN in 1982 with a 24-hour simulcast of CNN, then a newly founded news cable channel. After one year, KCNN changed its call sign to KPQP in 1983 and its format to adult standards; this format would last nearly 20 years and include another call sign change to KPOP in 1986. The station had been locally owned throughout its history until 1996, when it was purchased by Nationwide Communications, predecessor to iHeartMedia. Then in 2004, the station joined Air America Radio, a startup liberal talk radio network, and became KLSD. The liberal talk format stayed for three years. KLSD then had a sports format affiliated with Fox Sports Radio from 2007 to 2022. KLSD and a KGB station with a different frequency swapped formats in 2022, resulting in KLSD picking up its current conservative talk programming.

KLSD's schedule is primarily nationally syndicated shows: The Glenn Beck Radio Program, The Dana Loesch Show, The Mark Levin Show, The Jesse Kelly Show, Red Eye Radio and America in the Morning. Most hours begin with an update from CBS News Radio.
