Dr. Strangelove or: How I Learned to Stop Worrying and Love the Bomb, known simply and more commonly as Dr. Strangelove, is a 1964 satirical black comedy film that satirizes the Cold War fears of a nuclear conflict between the Soviet Union and the United States. The film was directed, produced, and co-written by Stanley Kubrick and stars Peter Sellers, George C. Scott, Sterling Hayden, and Slim Pickens. The film is loosely based on Peter George's thriller novel Red Alert (1958).

The story concerns an unhinged United States Air Force general who orders a pre-emptive nuclear attack on the Soviet Union. It separately follows the President of the United States, his advisors, the Joint Chiefs of Staff and a Royal Air Force exchange officer as they attempt to prevent the crew of a B-52 (who were following orders from the general) from bombing the Soviet Union and starting a nuclear war.

The film is often considered one of the best comedies ever made, as well as one of the greatest films of all time. In 1998, the American Film Institute ranked it twenty-sixth in its list of the best American movies (in the 2007 edition, the film ranked thirty-ninth), and in 2000, it was listed as number three on its list of the funniest American films. In 1989, the United States Library of Congress included Dr. Strangelove as one of the first 25 films selected for preservation in the National Film Registry for being "culturally, historically, or aesthetically significant".
