Minor
Alan: An honest sailor who is killed by the mutineers during the landing on the island and whose death scream is heard across the isle. The incident occurs just before Long John murders Tom.
Allardyce: One of the six members of Flint's Crew who, after burying the treasure and silver and building the blockhouse on Treasure Island, are all killed by Flint, who returns to his ship alone. Allardyce's body is lined up by Flint as a compass marker to the cache.
In Porto Bello Gold, one sailor on Flint's ship is named "Tom Allardyce". A lanky fellow with rather long, yellow hair, he is an antagonistic ringleader of sailors opposing Flint in at least two "fo'c'sle councils". Flint thinks they may present him with the Black Spot; he eventually challenges Allardyce to bring six friends and bury the treasure together.
According to The Adventures of Ben Gunn, his first name was "Nic", he was surgeon on Flint's crew, and Ben Gunn was his servant and friend from back home.
Job Anderson: The ship's boatswain and one of the leaders of the mutiny. He participates in the storming of the blockhouse and is killed by Gray while attacking Jim. He is probably one of Flint's old pirate hands, though this is never stated. Along with Hands and Merry, he tipped a Black Spot on Silver and forced Silver to start the mutiny before the treasure was found.
Mr. Arrow: The first mate of the Hispaniola. He is an alcoholic and is useless as a first mate. He disappears before they get to the island and his position is filled by Job Anderson. Silver had secretly given Mr. Arrow alcohol and he fell drunkenly overboard on a stormy night. In his BBC adaptation of 1977, John Lucarotti gives him the first name "Joshua". His first name was not stated in the novel.
Black Dog: Formerly a member of Flint's pirate crew, later one of Pew's companions who visits the Admiral Benbow to confront Billy Bones. He is spotted by Jim in Silver's tavern and slips out to be chased by two of Silver's men (in order to maintain the ruse that Silver and his men are not associated with him). Two fingers are missing from his left hand, and from his first appearance at the Admiral Benbow Inn, it appears Billy Bones may have previously attacked him and caused the injury.
Pew: A vicious, deadly, and sinister blind beggar who served as a member of Flint's crew. Despite his blindness, he proves to be a dangerous adversary and can even be considered a ringleader amongst his fellow crewmen. He is the second messenger to approach Billy Bones and the one to deliver the Black Spot. He is trampled to death by the horses of revenue officers riding to assist Jim and his mother after the raid on their inn. Silver claims Pew spent his share of Flint's treasure at a rate of £1,200 (equivalent to £126,153 in 2025) per year, and that for two years until his accident at the "Admiral Benbow", he begged, stole, and murdered. Stevenson avoided predictability by making the two most fearsome characters a blind man and an amputee. In the play Admiral Guinea (1892), Stevenson gives him the full name "David Pew". Stevenson's novel Kidnapped (1886) also features a dangerous blind man.
In Porto Bello Gold by Arthur D. Howden Smith, Pew fatally stabs Captain Murray, working in concert with Long John Silver. From the context, it seems that Silver means Pew when he addresses one man as "Ezra" just previously.
Mr. Dance: Chief revenue officer (titled Supervisor) who ascends with his men upon the Admiral Benbow, driving out the pirates, and saving Jim Hawkins and his mother. He then takes Hawkins to see the squire and the doctor.
Dogger: One of Mr. Dance's associates, who doubles Hawkins on his horse to the squire's house.
Captain J. Flint: A pirate who was captain of a ship called the Walrus, and who is dead before the events of the novel begin. In life he was the leader of the pirates and they refer to him often. He was the original possessor of the treasure, and buried it on the island. Long John Silver's parrot is named after him.
Abraham Gray: A ship's carpenter's mate on the Hispaniola. He is almost incited to mutiny but remains loyal to the Squire's side when asked to do so by Captain Smollett. He saves Hawkins' life by killing Job Anderson during an attack on the stockade, and he helps shoot the mutineers at the rifled treasure cache. He later escapes the island together with Jim Hawkins, Dr. Livesey, Squire Trelawney, Captain Smollett, Long John Silver, and Ben Gunn. He spends his part of the treasure on his education, marries, and becomes part owner of a full-rigged ship.
Israel Hands: The ship's coxswain and Flint's old gunner. He tries to murder Jim Hawkins, who shoots him in self-defence.
Harry: He is probably one of Flint's old pirate hands; one of those who "ran after Black Dog" at the Spyglass Inn.
Mr. and Mrs. Hawkins: The parents of Jim Hawkins. Mr. Hawkins dies early in the story.
John Hunter: A manservant of Squire Trelawney. Dr. Livesey considers him to be the most steady and capable of Livesey's servants to have in a fight. He accompanies Trelawney to the island but is later knocked unconscious in an attack on the stockade. He dies of his injuries while unconscious.
John: A mutineer who is injured while trying to storm the blockhouse. Throughout the latter narrative he is primarily referred to by Hawkins as 'the man with the bandaged head' and ends up being killed at the rifled treasure cache. He is probably one of Flint's old pirate hands, as his name is called by Blind Pew before Pew was killed at the Inn.
Dick Johnson: The youngest of the mutineers, who has a Bible. The pirates use one of its pages to make a Black Spot for Silver, only to have him predict bad luck on Dick for sacrilege. Soon becoming mortally ill with malaria, Dick ends up being marooned on the island after the deaths of George Merry and John.
Dirk: One of Flint's old pirate hands, he was a lookout for the ex-pirates in Pew's attack on the Inn
Richard Joyce: One of the manservants of Squire Trelawney who accompany the squire to the island, a mild-mannered valet inexperienced in firearms. He is shot through the head and killed by a mutineer during an attack on the stockade.
George Merry: A mutinous and hostile member of Silver's crew, who disobeys orders and occasionally challenges Silver's authority. With Anderson and Hands he launches the mutiny prematurely; he forces Silver to attack the blockhouse instead of waiting for the treasure to be found. He almost overthrew Silver's rule and forced Long John to take Jim as a hostage. Later killed at the empty cache just as he is about to kill both Silver and Hawkins.
Tom Morgan: An ex-pirate from Flint's old crew. He ends up marooned on the island with Dick and one other mutineer.
O'Brien: A mutineer who survives the attack on the blockhouse and escapes. He is later killed by Israel Hands in a drunken fight on the Hispaniola. He is referred to by Hawkins as the pirate 'with the red nightcap' throughout most of the narrative, until Hands reveals to Hawkins that the fellow was an Irishman named O'Brien.
Tom Redruth: The gamekeeper of Squire Trelawney. He accompanies the Squire to the island but is shot and mortally wounded by the mutineers as the captain's party are relocating from the ship to the stockade.
Tom: An honest sailor who is killed by Silver for refusing to join the mutiny.
Among other minor characters whose names are not revealed are the four pirates who were killed in an attack on the stockade along with Job Anderson; the pirate killed by the honest men minus Jim Hawkins the day before the attack on the stockade; the pirate killed by Ben Gunn the night before the attack; the pirate shot by Squire Trelawney when aiming at Israel Hands, who later died of his injuries; and the pirate marooned on the island along with Tom Morgan and Dick Johnson (features as Jerry Wilkins in the 1963 sequel Der Piratenkapitän, see below).
