The Pequod is a fictional 19th-century Nantucket whaling ship that appears in the 1851 novel Moby-Dick by American author Herman Melville. Pequod and her crew, commanded by Captain Ahab, are central to the story, which, after the initial chapters, takes place almost entirely aboard the ship during a three-year whaling expedition in the Atlantic, Indian and South Pacific oceans. Most of the characters in the novel are part of Pequods crew.

Ishmael, the novel's narrator, encounters the ship after he arrives in Nantucket and learns of three ships that are about to leave on three-year cruises. Tasked by his new friend, the Polynesian harpooneer Queequeg (or more precisely, Queequeg's idol-god, Yojo), to make the selection for them both, Ishmael, a self-described "green hand at whaling", goes to the Straight Wharf and chooses the Pequod.

Name

Ishmael says that Pequod was named for the Algonquian-speaking Pequot tribe of Native Americans.

Pequod is not unlike Ahab in this respect, since many of the rest of these missing elements have been replaced by the bones of the whales she hunts. She is not a new vessel, and with age would usually come some veneration and respect, which Ishmael tries to convey by using several historical references in his description of her. But in Pequods case this has been negated by the thick veneer of barbarity that has been overlaid onto the ship in the form of fantastic scrimshaw embellishment. Far from enjoying mere utilitarian replacements out of available whalebone, she has been ornately decorated, even to the whale teeth set into the railing that now resemble an open jaw. Like a fingerbone necklace on a cannibal, these adornments are clear evidence of Pequods success as a hunter and killer of whales.

The principal owners of the vessel are two well-to-do Quaker retired whaling captains, therefore "the other and more inconsiderable and scattered owners, left nearly the whole management of the ship's affairs to these two."
