Jack Tier, or the Florida Reef is a novel by James Fenimore Cooper first published in 1848 by New York publisher Burgess, Stringer & Co. Set during the Mexican–American War, the novel relates a twenty-year homosocial relationship verging on the homoerotic between a sailor and the captain of the boat. But by the end of the novel the sailor is the captain's wife, transforming the story into one of heterosexual love and passion.^[1][2]

The novel was first published serially in a magazine under the title Rose Budd in 1846.^[2] When commenting on the novel in the context of other novels about the Mexican-American War, critic Jaime Javier Rodríguez describes the novel as "an obscure work not always found in library stacks [thus it] remains largely unread but it too deserves attention."^[3]

Garden Key Light on Garden Key in the Dry Tortugas was used as the setting for the novel.^[4]
