In the 1975 film 'Jaws', what is the name of the island where the attacks occur?

In the 1975 film 'Jaws', the attacks occur on Amity Island. The fictional New England island community depends heavily on its summer beach tourism, which makes the mayor reluctant to close the beaches after the first shark attack.

Police Chief Martin Brody, played by Roy Scheider, wants to protect swimmers, while Mayor Larry Vaughn worries that warnings will damage the local economy. The conflict between public safety and commercial pressure drives much of the film's early story.

Amity Island is fictional, but many scenes were filmed on Martha's Vineyard, Massachusetts, especially in and around the town of Edgartown. That real filming location is a common source of confusion: Martha's Vineyard is not the island's name within the story. The film was adapted from Peter Benchley's 1974 novel and directed by Steven Spielberg.
