Billy Bones is a fictional character appearing in the first section of Robert Louis Stevenson's 1883 novel Treasure Island.

Though his down-payment for lodgings is adequate, even generous, he stays for many months and browbeats Jim Hawkins' father out of asking for more money even when his deposit has been spent.

[2] A heavily addicted alcoholic, the Captain terrorizes the customers of the Benbow with his swearing, singing and general bullying.

He is tended to by Dr. Livesey, who discovers the real name of the Captain to be Billy Bones when his arm is bared as a prelude to a surgical bloodletting and the name is found tattooed there.

He is plainly weakened by his stroke and the shock of Black Dog's visit, and at one point Hawkins even hears him sing a country love song, a gentle relic of his innocent days as a youth.
