KCRW (89.9 FM) is an NPR member station broadcasting from the campus of Santa Monica College in Santa Monica, California, where the station is licensed. KCRW airs original news and music programming in addition to programming from NPR and other affiliates. A network of repeaters and broadcast translators, as well as internet radio, allows the station to serve the Greater Los Angeles area and other communities in Southern California. The station's main transmitter is located in Los Angeles's Laurel Canyon district, adjacent to Mulholland Drive at the end of Briarcrest Road, and broadcasts in the HD radio format. It is one of two full NPR members in the Los Angeles area; Pasadena-based KPCC is the other.

KCRW was founded in 1945 to train servicemen returning from World War II in the then-new technology, FM broadcasting—hence its call letters, which stand for College Radio Workshop. It was a charter member of NPR in 1970, making Santa Monica College the second community college to own a public radio or television station.

Former KPFK program director Ruth Seymour became general manager in 1978 and retired in February 2010. Born Ruth Epstein to Russian-Polish Jewish immigrants, she grew up in the East Bronx, studied at Sholem Aleichem Folk School and the City College of New York, and married and divorced Jack Hirschman, adopting the name of her paternal great-grandfather in 1993 to become Ruth Hirschman Seymour. She developed a mix of music, news, and other spoken-word programming that now attracts over 500,000 listeners each week. She was also known for a feisty temperament and a spur-of-the-moment style that led to the nickname "Lady of the Iron Whim."

The current general manager is Jennifer Ferro. Ferro is also the President of the KCRW Foundation, which provides financial support and other resources to ensure that KCRW can maintain and expand its mission consistent with economic, social and technological developments. The KCRW Foundation board of directors is composed of business and community leaders; Monica J. Shilling, a partner at Kirkland & Ellis LLP, serves as chair.

The station airs programs from NPR, Public Radio International (PRI), American Public Media, and the BBC, a range of music programs and live in-studio performances, and locally produced news and culture programs. KCRW also airs programming created through their Independent Producer Project, a project KCRW created to support "the work of independent contributors," which includes programs like Strangers, UnFictional, and SoundsLA. The station has three live program streams—"On Air," "Eclectic 24" and "News 24"—and on-demand listening through the KCRW apps and podcasts.

In August 2013, KCRW released a new logo and brand design created by Los Angeles–based branding agency Troika Design Group.

KCRW is an affiliate of NPR. Music programming includes the station's music program Morning Becomes Eclectic.

Warren Olney hosts the station's news and public affairs programs, To the Point (nationally distributed by Public Radio International).
