Ghostbusters is a 1984 spooky sci-fi comedy film about three eccentric New York City parapsychologists. After they are fired from a university, they start their own business investigating and capturing ghosts.

It was followed by a sequel, Ghostbusters II (1989), and two animated television series, The Real Ghostbusters (later Slimer! And the Real Ghostbusters) and Extreme Ghostbusters. According to actor Dan Aykroyd, an all-CGI sequel (Ghostbusters III) has been confirmed for future production, with Bill Murray to provide voice talent.

Ghostbusters was released in the United States on June 8, 1984, starring Bill Murray, Dan Aykroyd, Harold Ramis, Rick Moranis, Sigourney Weaver, Annie Potts and Ernie Hudson. The film grossed approximately USD$240 million in the U.S. and over $50 million abroad during its theatrical run, more than the second "Indiana Jones" installment, making it easily the most successful film of that year, and the most successful comedy of the 1980s.

In 2000, readers of Total Film magazine voted Ghostbusters the 44th greatest comedy film of all time. The American Film Institute ranked it 28th in its list of the top 100 comedies of all time (in their "AFI's 100 Years...100 Laughs" list). In 2005, IGN voted Ghostbusters the greatest comedy ever. In 2006, Bravo's ranked Ghostbusters 76 on their "100 Funniest Movies" list.
