The D'Artagnan Romances are a set of three 19th-century novels by Alexandre Dumas (1802–1870), telling the story of the 17th-century musketeer D'Artagnan.
Dumas based the character and attributes of D'Artagnan on captain of musketeers Charles de Batz-Castelmore d'Artagnan (c. 1611–1673) and the portrayal was particularly indebted to D'Artagnan's semi-fictionalized memoirs as written up 27 years after the hero's death by Gatien de Courtilz de Sandras (published 1700).
The three novels are:
Four further sequels to the D'Artagnan books – the novels The Son of Porthos (1883) and D'Artagnan Kingmaker (1900), The King’s Passport (1925), D'Artagnan, the sequel to the Three Musketeers – were written and published after Dumas's death. D'Artagnan does not appear in the first novel, which, although written by Paul Mahalin, was published under the pen name "Alexandre Dumas" and is still sold as such. The second novel was supposedly based on one of Dumas' plays. The last two were written by H. Bedford-Jones.
