PM, sometimes referred to as the PM programme to avoid ambiguity, is BBC Radio 4's long-running early evening news and current affairs programme.

PM was a liberal leaning daily newspaper published in New York City by Ralph Ingersoll from June 1940 to June 1948 and financed by Chicago millionaire Marshall Field III.

The origin of the name is unknown, although Ingersoll recalled that it probably referred to the fact that the paper appeared in the afternoon; The New Yorker reported that the name had been suggested by Lillian Hellman. (There is no historical evidence for the suggestion that the name was an abbreviation of Picture Magazine.) The paper borrowed many elements from weekly news magazines, such as many large photos and at first was bound with staples. In an attempt to be free of pressure from business interests, it did not accept advertising. These departures from the norms of newspaper publishing created excitement in the industry. Some 11,000 people applied for the 150 jobs available when the publication first hired staff.

There were accusations that the paper was Communist-dominated, but a thesis by Anya Schiffrin concluded that the paper frequently opposed the policies of the Communist Party and got into editorial fights with the CP's paper, the Daily Worker.

PM is one of the Australian Broadcasting Corporation's flagship current-affairs radio programs, and is one of Australia's longest-running productions. It is the sister program to AM. Currently presented by Mark Colvin, it was first heard 7 July 1969 and is currently broadcast on ABC Radio National and ABC Local Radio.
