The Tales of Beedle the Bard is also a plot device in the seventh novel of the Harry Potter series, Deathly Hallows, in which it is bequeathed to Hermione Granger by Albus Dumbledore. The book is described as a popular collection of Wizarding children's fairy tales, thus while Ron Weasley is familiar with the stories, Harry Potter and Hermione Granger had not previously heard them due to their non-magical upbringing.

The edition Hermione received in chapter seven in Dumbledore's will is a copy of the original edition of fictional books in the novel. It is described as an ancient-looking small book with its binding "stained and peeling in places". In the novel it is also said the book has a title on its cover, written in embossed runic symbols.

The book acts as the vehicle for introducing the Deathly Hallows. Above the story The Tale of the Three Brothers, Hermione Granger finds a strange symbol which later is revealed by Xenophilius Lovegood to be the symbol of the Hallows. The triangle from the symbol represents the Invisibility Cloak, the circle inside the triangle symbolizes the Resurrection Stone, and the vertical line represents the Elder Wand.
