Samuel Scott, 15, believed to be the first person killed in connection with the ill-fated ship, will get the headstone Saturday at Belfast City Cemetery during the Feile an Phobail festival, the BBC reported.
His body had lain in an unmarked grave in the cemetery since 1910, when he suffered a fractured skull in a fall while working with a riveting team at Harland and Wolff shipyard in Belfast, the Belfast Telegraph reported.
The headstone unveiling comes after publication of a new book, "Spirit of the Titanic," in which Samuel, the main character, is a ghost that haunts the ship during its voyage. The book also includes characters such as the Titanic's captain, Edward Smith.
"It really seems to have hit home," said author Nicola Pierce. "The kids really do seem to like it."
