The Holy Blood and the Holy Grail (retitled Holy Blood, Holy Grail in the United States) is a book by Michael Baigent, Richard Leigh and Henry Lincoln.

The book was first published in 1982 by Jonathan Cape in London, as an unofficial follow-up to three BBC Two TV documentaries that were part of the Chronicle series. The paperback version was first published in 1983 by Corgi books. A sequel to the book, called The Messianic Legacy, was originally published in 1986. The original work was reissued in an illustrated hardcover version with exclusive new material in 2005. One of the books that the authors claim influenced the project was L'Or de Rennes (later re-published as Le Trésor Maudit), a 1967 book by Gérard de Sède, with the collaboration of Pierre Plantard.

In The Holy Blood and the Holy Grail, the authors put forward a hypothesis, that the historical Jesus married Mary Magdalene, had one or more children, and that those children or their descendants emigrated to what is now southern France. Once there, they intermarried with the noble families that would eventually become the Merovingian dynasty, whose special claim to the throne of France is championed today by a secret society called the Priory of Sion. They concluded that the legendary Holy Grail is simultaneously the womb of Mary Magdalene and the sacred royal bloodline she gave birth to.

An international bestseller upon its release, The Holy Blood and the Holy Grail spurred interest in a number of ideas related to its central thesis. Response from professional historians and scholars from related fields was universally negative. They argued that the bulk of the claims, ancient mysteries, and conspiracy theories presented as facts are pseudohistorical. The book's ideas were considered blasphemous enough for the book to be banned in some Roman Catholic-dominated countries such as the Philippines.
