KPFK 90.7 FM, based in North Hollywood, California, is a listener-sponsored, non-commercial radio station serving Southern California. Established in July 1959, it was the second station founded by the Pacifica Foundation, a nonprofit organization dedicated to promoting free speech and independent media. With a 110,000-watt transmitter atop Mount Wilson, KPFK boasts one of the most powerful FM signals in the western United States, reaching audiences from the Mexican border to Santa Barbara and beyond.​

As a progressive media outlet, KPFK challenges corporate media narratives by providing a platform for underrepresented communities and alternative perspectives. Its programming includes a diverse mix of news, public affairs, arts, and music, reflecting the rich cultural tapestry of its listening area. The station broadcasts primarily in English but also offers 22 hours of Spanish-language programming each week, catering to the region’s diverse population.​

Operated largely by volunteers and funded through listener contributions, KPFK embodies the Pacifica Foundation’s mission to promote peace, social justice, and cultural diversity through free speech and creative expression. The station’s extensive reach and diverse programming make it a vital voice for communities across Southern California and beyond.
