Shutter Island is a best-selling novel by Dennis Lehane, published by Harper Collins in April 2003. A film adaptation (Shutter Island (film)) was released in February 2010.

Lehane has said he sought to write a novel that would be a homage to Gothic (Gothic fiction) settings, B movies, and pulp (Pulp magazine). He described the novel as a hybrid of the works of the Bront� sisters (Bront�) and the 1956 film Invasion of the Body Snatchers. His intent was to write the main characters in a position where they would lack 20th century resources such as radio communications. He also structured the book to be more taut than his previous book, Mystic River (Mystic River (novel)).
