Pym
Arthur Gordon Pym, the narrator of his tale of a sea expedition gone terribly awry, is a young man from a respectable background who has a rather melancholy disposition. He becomes interested in the sea and is stowed away on a ship by his friend Augustus, whose father is the captain of the voyage. Pym experiences many terrible things during his journey - near interment in the ship's hold, madness, shipwreck, cannibalism, starvation, an encounter with vicious natives, and a surreal journey to the unexplored South Pole. He is both a passive character - things seem to happen to him - as well as an individual who keeps his wits when others succumb to their mental and/or physical problems. He vacillates between despair and hope. It is revealed at the end of the work by Poe, the editor, that Pym made it home safely from his travels but died in an unforeseen manner before he could provide Poe with the last portion of the narrative.
Augustus Barnard
The son of Captain Barnard and closest friend of Pym. Augustus grows up on the sea and inspires Pym with his fantastical tales. He sneaks Pym aboard the Grampus and is unfortunately caught up in the ship's mutiny. He is wounded in the attack made by himself, Pym, and Peters to take back the ship; he later dies of his wounds as well as starvation and exposure. Augustus is energetic, amiable, and intelligent.
Captain Barnard
Augustus's father and captain of the Grampus. A personal grievance of the mate leads to a mutiny and the Captain is cast asea on a small boat. He is not heard from again.
Pym's grandfather
This venerable gentleman, not given a proper name in the text, is a successful lawyer. His objections to Pym's desire to go to sea leads to Pym's sneaking aboard the Grampus.
Dirk Peters
The son of a Native American woman and a fur-trader, Peters is short, strong, and fierce. He has an animated face and wears a wig of any hair-like material he can find. He possesses equanimity of temperament as well as discernment and intelligence. He is responsible for taking back the Grampus and keeping the men alive through their misadventures. Later on the island of Tsalal he saves Pym's life. Peters is a spiritual, cerebral figure even though he has brute strength.
Seymour
The black cook of the Grampus who helps lead the mutiny. He prefers to go on a whaling mission rather than resort to piracy. He is influential and, as described by Augustus, is a "perfect demon".
The mate
The mate of the Grampus, whose personal vendetta against Captain Barnard leads to the ill-fated mutiny. He prefers to take the vessel on a piratical journey and tries to win others to his idea. Violent and immoral, he possibly poisons Hartman Rogers. He is literally frightened to death when he sees Pym dressed up as Rogers's corpse.

Richard Parker
One of the mutineers, his life is spared by Peters, Pym, and Augustus when they take back the ship.

It is his idea to resort to cannibalism by drawing straws and having one man give up his life for the others, but unfortunately he is the one who draws the short straw.
