Alternative Radio is a weekly one-hour public affairs program offered free to all public radio stations in the U.S., Canada, Europe, South Africa, Australia, and on short-wave on Radio for Peace International.

AR provides information, analyses and views that are frequently ignored or distorted in other media. Established in 1986, AR is dedicated to the founding principles of public broadcasting, which urge that programming serve as "a forum for controversy and debate," be diverse and "provide a voice for groups that may otherwise be unheard." The project is entirely independent, sustained solely by individuals who buy transcripts and tapes of programs. Its headquarters, with five paid staff, are located in Boulder, Colorado. AR reaches over 125 radio stations and millions of listeners. AR is part of the non-profit Institute for Social and Cultural Change.
